Misiyano muhukuru hwechinhu inogona kutsanangura zvishoma mutsauko weRBER kukosha pakati pemadhiraivha modhi uchishandisa iyo imwechete tekinoroji, i.e. MLC kana SLC. (Ona Tafura 1 kuti uwane mhedziso yezvinyorwa zvemhando dzakasiyana-siyana dzakabatanidzwa muchidzidzo chino).
Semuenzaniso, 2 SLC modhi ine 34nm lithography (mienzaniso SLC-A uye SLC-D) ine RBER iyo iri kurongeka kwehukuru hwepamusoro kupfuura iyo yemhando mbiri ine 2nm microelectronic lithography (mienzaniso SLC-B uye SLC-C). Panyaya yemhando dzeMLC, iyo 50nm modhi chete (MLC-B) ine yepakati RBER iri 43% yakakwira kupfuura mamwe matatu ane 50nm lithography. Uyezve, kusiyana uku muRBER kunowedzera nechikamu che 3 sezvo madhiraivha apera, sezvakaratidzwa muMufananidzo 50. Pakupedzisira, thinner lithography inogona kutsanangura iyo yakakwirira RBER ye eMLC drives kana ichienzaniswa neMLC drives. Pakazara, isu tine humbowo hwakajeka hwekuti lithography inobata RBER.
4.2.5. Kuvapo kwezvimwe zvikanganiso.
Takaongorora hukama huri pakati peRBER nemamwe marudzi ezvikanganiso, zvakadai sezvikanganiso zvisingagadziriswi, zvikanganiso zvekufamba kwenguva, nezvimwewo, kunyanya, kana kukosha kweRBER kuchikwira mushure memwedzi wekusangana kune mamwe marudzi ezvikanganiso.
Mufananidzo 1 unoratidza kuti nepo RBER yemwedzi wapfuura ichifanotaura nezveramangwana RBER kukosha (yekubatanidza coefficient yakakura kupfuura 0,8), hapana kuwirirana kwakakosha pakati pezvikanganiso zvisina kurongeka uye RBER (boka rekurudyi rezvinhu muMufananidzo 1). Kune mamwe marudzi ezvikanganiso, coefficient yekubatanidza yakatodzika (isina kuratidzwa mumufananidzo). Isu takaongororazve hukama pakati peRBER uye zvikanganiso zvisina kugadziriswa muChikamu 5.2 chepepa rino.
4.2.6. Kufurira zvimwe zvinhu.
Takawana humbowo hwekuti pane zvinhu zvine chekuita neRBER izvo data yedu yaisagona kuzvidavirira. Kunyanya, takaona kuti RBER yemhando yakapihwa dhisiki inosiyana zvichienderana nesumbu rinoiswa dhisiki. Muenzaniso wakanaka ndeye Figure 4, iyo inoratidza RBER sebasa re PE madhiraini eMLC-D madhiraivha mumasumbu matatu akasiyana (dashed mitsetse) uye inoienzanisa neRBER yeiyi modhi inoenderana nehuwandu hwehuwandu hwemadhiraivha (solid line). Isu tinoona kuti misiyano iyi inoenderera kunyangwe isu tichidzikamisa pesvedzero yezvinhu zvakaita sezera redhisiki kana nhamba yekuverenga.
Imwe tsananguro inogoneka yeiyi misiyano mumhando yebasa remasumbu, sezvatinoona kuti masumbu ane mitoro yebasa ine reshiyo yepamusoro yekuverenga / kunyora ine RBER yepamusoro.
Mupunga. 4 a), b). Median RBER kukosha senge basa rePE kutenderera kune matatu akasiyana masumbu uye kutsamira kweyekuverenga / kunyora reshiyo pahuwandu hwePE kutenderera kwemapoka matatu akasiyana.
Semuyenzaniso, Mufananidzo 4(b) unoratidza mareshiyo ekuverenga/kunyora emasumbu akasiyana eMLC-D drive modhi. Zvisinei, chiyero chekuverenga / kunyora hachitsananguri kusiyana pakati pemasumbu emhando dzose, saka panogona kunge kune zvimwe zvinhu izvo data yedu isingazvidavirire, zvakadai semamiriro ezvakatipoteredza kana mamwe maitiro emabasa ekunze.
4.3. RBER panguva yekukurumidza kusimba kuyedzwa.
Basa rakawanda resainzi, pamwe nemiedzo inoitwa kana uchitenga midhiya pachiyero cheindasitiri, inofanotaura kuvimbika kwemidziyo mumunda zvichibva pamhedzisiro yekukasira kusimba bvunzo. Isu takasarudza kuona kuti mhedzisiro yebvunzo dzakadaro inoenderana sei neruzivo runoshanda mukushanda yakasimba-nyika yekuchengetedza midhiya.
Ongororo yemhedzisiro yebvunzo yakaitwa uchishandisa yakajairika yakakwirisa bvunzo nzira yemidziyo inopihwa kuGoogle data nzvimbo yakaratidza kuti munda RBER kukosha kwakakwira zvakanyanya kupfuura zvakafanotaurwa. Semuenzaniso, yeEMLC-modhi, iyo yepakati RBER yemadhiraivha anoshanda mumamiriro ezvinhu emumunda (pakupera kwekuyedza nhamba yePE cycles yakasvika 600) yaive 1e-05, nepo maererano nemhedzisiro yepreliminary kukurumidza kuyedza, iyi RBER. kukosha kunofanirwa kuenderana neanopfuura 4000 PE cycles. Izvi zvinoratidza kuti zvakanyanya kuoma kunyatsofanotaura kukosha kweRBER mumunda zvichibva pakufungidzira kweRBER kunowanikwa kubva kuongororo dze laboratori.
Isu takacherekedzawo kuti mamwe marudzi ezvikanganiso zvakaoma kubereka panguva yekumhanyisa kuyedzwa. Semuenzaniso, kana iri MLC-B modhi, ingangoita 60% yedhiraivha mumunda inosangana nezvikanganiso zvisingagadzirike uye ingangoita 80% yedhiraivha inogadzira mabhururu akaipa. Nekudaro, panguva yekumhanyisa kuyedzwa kwekutsungirira, hapana kana chimwe chezvitanhatu zvacho chakawana chero zvikanganiso zvisina kugadziriswa kudzamara madhiraivha asvika kanopfuura katatu PE cycle muganho. Kune eMLC modhi, kukanganisa kusingagadziriswe kwakaitika mune inodarika 80% yemadhiraivha mumunda, nepo panguva yekukurumidza kuyedza kukanganisa kwakadaro kwakaitika mushure mekusvika 15000 PE kutenderera.
Isu takatarisawo iyo RBER yakashumwa mubasa rekare rekutsvagisa, iro raive rakavakirwa pakuyedza munzvimbo inodzorwa, uye tikagumisa kuti huwandu hwehunhu hwaive hwakakura zvakanyanya. Somuenzaniso, L.M. Grupp nevamwe mune yavo 2009 -2012 basa reshumo RBER tsika dzemadhiraivha ari pedyo nekusvika PE kutenderera miganho. Semuyenzaniso, kumidziyo yeSLC neMLC ine saizi yelithography yakafanana neanoshandiswa mubasa redu (25-50nm), kukosha kweRBER kunotangira pa1e-08 kusvika pa1e-03, ine mhando dzemadhiraivha dzakawanda dzakaedzwa dzine kukosha kweRBER pedyo ne1e- 06.
Muchidzidzo chedu, mhando nhatu dzekutyaira dzakasvika pamuganhu wePE cycle dzaive neRBER kubva pa3e-08 kusvika 8e-08. Kunyangwe tichifunga kuti nhamba dzedu dzakaderera uye dzinogona kunge dzakakura zvakapetwa kagumi nenhanhatu kana tichifunga nezve 16th percentile yeRBER, hunhu hwedu huchiri kuderera zvakanyanya.
Pakazere, nepo munda chaiwo RBER hunhu hwakakwira pane hwakafanotaurwa huyero hunoenderana nekukasira kusimba kuyedzwa, achiri akaderera pane mazhinji maRBER emidziyo yakafanana yakataurwa mune mamwe mapepa ekutsvagisa uye akaverengerwa kubva murabhoritari bvunzo. Izvi zvinoreva kuti haufanirwe kuvimba nemunda wakafanotaurwa RBER tsika dzakatorwa kubva mukukurumidza kusimba kuyedzwa.
5. Zvikanganiso zvisingagadzirisiki.
Tichifunga nezvekupararira kwekukanganisa kusingagadziriswe (UEs), izvo zvakakurukurwa muChikamu 3 chepepa rino, muchikamu chino tinoongorora maitiro avo zvakadzama. Isu tinotanga nekukurukura kuti ndeipi metric yekushandisa kuyera UE, kuti inobatana sei neRBER, uye kuti UE inobatwa sei nezvinhu zvakasiyana.
5.1. Nei chiyero cheUBER chisina musoro.
Metric yakajairwa inoratidza zvikanganiso zvisingagadzirisike ndeye UBER isingagadzirisike bit kukanganisa mwero, kureva, reshiyo yehuwandu hwezvisingagadzirike zvikanganiso zvebhiti kusvika kuhuwandu hwemabhiti akaverengwa.
Iyi metric inonyatso fungidzira kuti nhamba yezvikanganiso zvisingagadzirisike neimwe nzira inosungirirwa kunhamba yemabhiti akaverengwa, uye nekudaro inofanira kugariswa nenhamba iyi.
Iyi fungidziro inoshanda kune zvikanganiso zvinogadziriswa, apo nhamba yezvikanganiso zvakaonekwa mumwedzi wakapihwa inowanikwa ichienderana zvakanyanya nenhamba yekuverenga panguva imwe chete yenguva (Spearman correlation coefficient yakakura kupfuura 0.9). Chikonzero chekubatana kwakasimba kwakadaro ndechokuti kunyange chidimbu chimwe chakaipa, chero bedzi chichigadziriswa uchishandisa ECC, chicharamba chichiwedzera nhamba yezvikanganiso nekushanda kwekuverenga kwega kwega kunowanikwa naro, sezvo kuongororwa kwesero rine bhiti rakaipa riri. isina kururamiswa nekukurumidza kana kukanganisa kwaonekwa (madhisiki anongogara achinyorazve mapeji ane mabhiti akakuvadzwa).
Kufungidzira kwakafanana hakushandi kune zvikanganiso zvisingagadzirisiki. Kukanganisa kusingagadzirisike kunodzivisa kuenderera mberi kwekushandisa kweyakakuvadzwa block, saka kana yangoonekwa, block yakadaro haizokanganisa huwandu hwekukanganisa mune ramangwana.
Kuti tisimbise zviri pamutemo fungidziro iyi, takashandisa zviyero zvakasiyana-siyana kuyera hukama pakati pehuwandu hwekuverenga mumwedzi wakapihwa wehupenyu hwe diski uye nhamba yezvikanganiso zvisingagadzirisiki panguva imwe chete yenguva, kusanganisira akasiyana coefficients coefficients (Pearson, Spearman, Kendall) , pamwe chete nekuongorora kwekuona magirafu. Mukuwedzera kune nhamba yezvikanganiso zvisingagadziriswi, takatarisawo kuwanda kwezviitiko zvekukanganisa zvisingakwanisi (kureva, mukana wekuti diski ichava nechiitiko chimwe chete chakadaro panguva yakatarwa) uye hukama hwavo hwekuverenga maitiro.
Hatina kuwana humbowo hwekubatana pakati pehuwandu hwekuverenga uye nhamba yezvikanganiso zvisina kurongeka. Kune ese madhiraivha emhando, iyo coefficient yekubatanidza yaive pazasi 0.02, uye magirafu haana kuratidza chero kuwedzera kweEU sezvo nhamba yekuverenga yakawedzera.
MuChikamu 5.4 chepepa rino, tinokurukura kuti kunyora nekudzima mashandiro zvakare haana hukama nekukanganisa kusingagadziriswe, saka imwe tsananguro yeUBER, iyo yakajairwa nekunyora kana kudzima mashandiro pachinzvimbo chekuverenga mashandiro, haina chirevo.
Naizvozvo tinogumisa kuti UBER haisi metric ine musoro, kunze kwekunge ichiedzwa munzvimbo dzakadzorwa uko nhamba yekuverenga inotangwa nemuongorori. Kana UBER ikashandiswa semetric panguva yekuyedzwa kwemunda, inodzikisa zvisirizvo mwero wekukanganisa kumadhiraivha ane yakakwira kuverenga kuverenga uye nekunyepedzera mwero wekukanganisa kwemadhiraivha ane yakaderera kuverenga kuverenga, sezvo zvikanganiso zvisingagadzirisike zvichiitika zvisinei nehuwandu hwekuverenga.
5.2. Zvikanganiso zvisina kugadziriswa uye RBER.
Kukoshera kweRBER kunotsanangurwa nenyaya yekuti inoshanda seyero yekuona kuvimbika kwese kwedhiraivha, kunyanya, zvichibva pamukana wekukanganisa kusingagadziriswe. Mubasa ravo, N. Mielke et al muna 2008 ndivo vaive vekutanga kupa pfungwa yekutsanangura iyo inotarisirwa isingagadziriswe kukanganisa kukanganisa sebasa reRBER. Kubva ipapo, vazhinji vanogadzira masisitimu vakashandisa nzira dzakafanana, dzakadai sekufungidzira chiyero chinotarisirwa chisingagadziriswe chikanganiso sebasa reRBER uye ECC mhando.
Chinangwa chechikamu ichi ndechekuratidza kuti RBER inofanotaura sei zvikanganiso zvisina kurongeka. Ngatitangei neFigure 5a, iyo inoronga iyo yepakati RBER kune akati wandei ekutanga-yechizvarwa madhiraivha mamodheru achipesana nezana remazuva avaishandiswa akawana zvisingagadziriswe zvikanganiso zveEU. Zvinofanira kucherechedzwa kuti mamwe emhando gumi nematanhatu anoratidzwa mugirafu haana kuiswa muTebhu 16 nekuda kwekushaikwa kweruzivo rwekuongorora.
Mupunga. 5a. Hukama pakati pemedian RBER uye zvikanganiso zvisingagadzirike kune akasiyana madhiraivha modhi.
Mupunga. 5b. Hukama pakati pemedian RBER uye zvikanganiso zvisingagadzirisike kune akasiyana madhiraivha emhando imwe chete.
Rangarira kuti ese mamodheru mukati mechizvarwa chimwe anoshandisa imwechete ECC michina, saka misiyano pakati pemamodheru yakazvimirira pane ECC misiyano. Hatina kuona kuwirirana pakati peRBER neEU zviitiko. Isu takagadzira iyo yakafanana chirongwa cheiyo 95th percentile RBER maringe neUE mukana uye zvakare hatina kuona kuwirirana.
Tevere, takadzokorora ongororo padanho regranular yedhiraivha yega yega, kureva kuti, takaedza kuona kana paive nemadhiraivha uko ukoshi hweRBER hwepamusoro hunoenderana neyepamusoro UE frequency. Semuenzaniso, Figure 5b inoronga iyo yepakati RBER kune yega yega yeMLC-c modhi maringe nenhamba yeUEs (mhedzisiro yakafanana neyakawanikwa ye95th percentile RBER). Zvekare, hatina kuona chero kuwirirana pakati peRBER neEU.
Pakupedzisira, takaita ongororo yenguva chaiyo yekuongorora kana mwedzi yekushanda yemadhiraivha ane RBER yepamusoro ingaenderana nemwedzi yakaitika maUE. Mufananidzo 1 watove wakaratidza kuti coefficient yekubatanidza pakati pezvikanganiso zvisingagadziriswi uye RBER yakaderera zvikuru. Isu takaedzawo nenzira dzakasiyana dzekuronga mukana weEU sebasa reRBER uye hatina kuwana humbowo hwekubatana.
Nekudaro, isu tinogumisa kuti RBER inyowani isingavimbike yekufembera UE. Izvi zvinogona kureva kuti nzira dzekukundikana dzinotungamirira kuRBER dzakasiyana nemaitiro anotungamirira kune zvikanganiso zvisingagadziriswi (somuenzaniso, zvikanganiso zviri mumasero ega ega maererano nezvinetso zvakakura zviri kuitika nemudziyo wose).
5.3. Kukanganisa kusingagadziriswe uye kupera uye kubvarura.
Sezvo kupera simba riri rimwe rematambudziko makuru ekurangarira flash, Mufananidzo 6 unoratidza mukana wezuva nezuva wezvisingagadziriswe zvikanganiso zvekutyaira sebasa rePE cycles.
Mufananidzo 6. Mukana wezuva nezuva wekuitika kwezvikanganiso zvisingagadziriswi zvekutyaira zvichienderana nePE cycles.
Isu tinocherekedza kuti mukana weEU unowedzera kuenderera nezera rekutyaira. Zvisinei, sezvakaita RBER, kuwedzera kunononoka pane zvinowanzofungidzirwa: magirafu anoratidza kuti maUE anokura mumutsara pane kuwedzera nePE cycles.
Mhedziso mbiri dzatakaita kuRBER dzinoshandawo kuUEs: kutanga, hapana kuwedzera kwakajeka kwekukanganisa kwekugona kana PE cycle muganhu wasvika, semufananidzo 6 weMLC-D model iyo PE cycle limit inosvika 3000. Chechipiri, Chechipiri, Chechipiri, Chechipiri , mwero wekukanganisa unosiyana pakati pemhando dzakasiyana, kunyangwe mukati mekirasi imwechete. Nekudaro, misiyano iyi haina kukura seRBER.
Chekupedzisira, mukutsigira zvatakawana muChikamu 5.2, takaona kuti mukati mekirasi imwe chete yemuenzaniso (MLC vs. SLC), mamodheru ane maRBER akaderera pane imwe nhamba yakapihwa yePE cycles handizvo izvo zvine yakaderera. mukana wekuitika kweEU. Semuyenzaniso, pamusoro pe3000 PE cycles, MLC-D modhi dzaive neRBER values ββyakadzikira neka4 pane MLC-B modhi, asi mukana weUE wenhamba imwechete yePE cycles yaive yakakwirira zvishoma kune MLC-D modhi pane yeMLC-B. mienzaniso.
Mufananidzo 7. Mwedzi wega wega mukana wekuitika kwezvikanganiso zvisingagadziriswi zvemotokari sebasa rekuvapo kwezvikanganiso zvekare zvemarudzi akasiyana-siyana.
5.4. Zvikanganiso zvisingagadzirisiki uye mutoro webasa.
Nezvikonzero zvakafanana izvo basa rekuita rinogona kukanganisa RBER (ona Chikamu 4.2.3), inogona kutarisirwa kukanganisawo EU. Semuyenzaniso, sezvo takaona kuti kuverenga kukanganisa kukanganisa kunokanganisa RBER, kuverenga mashandiro anogona zvakare kuwedzera mukana wekukanganisa kusingagadziriswe.
Takaita ongororo yakadzama pamabatiro ebasa reEU. Nekudaro, sezvakataurwa muChikamu 5.1, isu hatina kuwana hukama pakati peEU nehuwandu hwekuverenga. Takadzokorora ongororo imwechete yekunyora nekudzima mashandiro uye zvakare takaona pasina kuwirirana.
Ziva kuti pekutanga kuona, izvi zvinoita sekunge zvichipokana nekutarisa kwatakaita kare kuti zvikanganiso zvisina kurongeka zvine hukama nePE cycles. Naizvozvo, munhu anogona kutarisira kuwirirana nehuwandu hwekunyora uye kudzima mashandiro.
Nekudaro, mukuongorora kwedu kukanganiswa kwePE cycles, takafananidza huwandu hwezvikanganiso zvisina kurongeka mumwedzi wakapihwa nehuwandu hwehuwandu hwePE cycles dzakasangana nedhiraivha muhupenyu hwayo hwese kusvika parizvino kuitira kuyera mhedzisiro yekupfeka. Pataidzidza kukanganisa kwebasa rekushanda, takatarisa mwedzi yekushanda kwemotokari iyo yakanga ine nhamba yepamusoro yekuverenga / kunyora / kudzima mabasa mune imwe mwedzi, iyo yaivawo nemukana mukuru wekukonzera kukanganisa kusingagadziriswi, kureva, isu hatina kutora verenga nhamba yese yekuverenga/kunyora/kudzima mabasa.
Nekuda kweizvozvo, takasvika pakugumisa kuti kuverenga kukanganisa kukanganisa, kunyora kukanganisa kukanganisa, uye zvikanganiso zvekudzima zvisina kukwana hazvisi izvo zvinonyanya kukosha mukuvandudza zvikanganiso zvisingagadzirisiki.
