Mangwanani ano muSeoul, South Korea, Intel akabata "Memory and Storage Day 2019" chiitiko chakatsaurirwa zvirongwa zvemangwana mundangariro uye solid-state drive musika. Ikoko, vamiririri vekambani vakataura nezvematambudziko emberi, kufambira mberi kweshanu-bit plc nand (penta level cell) uye kumwe kusimudzira tekinoroji iyo inoronga kusimudzira pamakore anouya. Intel yakataurawo nezve chishuwo chayo chekuunza isina-inotenderera RAM mumakomputa edesktop munguva refu uye nezve mhando nyowani dzeanozivikanwa SSDs echikamu ichi.
Chikamu chisingatarisirwi chekuratidzwa kweIntel nezve zvirikuenderera mberi yaive nyaya yePLC NAND - yakatonyanya kuomarara mhando yekurangarira flash. Kambani inosimbisa kuti mumakore maviri apfuura, huwandu hwedata hwakagadzirwa munyika hwakapetwa kaviri, saka madhiraivha akavakirwa pane mana-bit QLC NAND haasisiri kuita senge mhinduro yakanaka kudambudziko iri - indasitiri inoda dzimwe sarudzo nepamusoro. kuchengetedza density. Iyo inobuda inofanirwa kunge iri Penta-Level Cell (PLC) flash memory, sero rega rega rinochengeta mabhiti mashanu edata kamwechete. Nekudaro, iyo hierarchy yemhando yekurangarira flash ichakurumidza kutaridzika seSLC-MLC-TLC-QLC-PLC. Iyo PLC NAND itsva ichakwanisa kuchengeta kashanu data rakawanda zvichienzaniswa neSLC, asi, hongu, nekuita kwakaderera uye kuvimbika, sezvo mutongi achafanira kusiyanisa pakati pemakumi matatu nembiri nyika dzekuchaja yesero kunyora nekuverenga mabhiti mashanu. .
Izvo zvakakosha kuti uzive kuti Intel haisi yega mukuda kwayo kugadzira kunyange denser flash memory. Toshiba akataurawo nezve hurongwa hwekugadzira PLC NAND panguva yeFlash Memory Summit yakaitwa muna Nyamavhuvhu. Nekudaro, tekinoroji yeIntel yakasiyana zvakanyanya: kambani inoshandisa anoyangarara-gedhi ndangariro maseru, nepo Toshiba madhizaini akavakwa akatenderedza macheji-akavakirwa maseru. Nekuwedzera kwehuwandu hwekuchengetedza ruzivo, gedhi rinoyangarara rinoita seyakanakisa mhinduro, nekuti inoderedza kuwirirana uye kuyerera kwechaji mumaseru uye inoita kuti ikwanise kuverenga data nezvikanganiso zvishoma. Mune mamwe mazwi, dhizaini yeIntel inokodzera zvirinani kuwedzera density, iyo inosimbiswa nemhedzisiro yebvunzo yekutengeserana inowanikwa QLC NAND yakagadzirwa uchishandisa akasiyana matekinoroji. Miedzo yakadai inoratidza kuti kuderedzwa kwedata muQLC ndangariro masero anoenderana negedhi rinoyangarara kunoitika kaviri kusvika katatu zvishoma pane muQLC NAND maseru ane musungo wekuchaja.
Tichipesana nemamiriro ezvinhu aya, iyo ruzivo iyo Micron yakafunga kugovera kusimudzira kwayo flash memory neIntel, pakati pezvimwe zvinhu, nekuda kwechishuwo chekuchinja kushandisa maseru ekubhadharisa, inotaridzika kunakidza. Intel inoramba yakazvipira kune yekutanga tekinoroji uye yakarongeka inoishandisa mune zvese zvitsva mhinduro.
Pamusoro pePLC NAND, iyo ichiri kugadziridzwa, Intel inotarisira kuwedzera huwandu hwekuchengetera ruzivo mune flash memory nekushandisa mamwe, anodhura matekinoroji. Kunyanya, kambani yakasimbisa shanduko yave pedyo kusvika pakugadzirwa kwakawanda kwe96-layer QLC 3D NAND: ichashandiswa mukutyaira kutsva kwevatengi. .
Izvi zvichateverwa nekugona kugadzirwa kwe144-layer QLC 3D NAND - icharova madhiraivha ekugadzira gore rinouya. Zvinoda kuziva kuti Intel kusvika parizvino yaramba chero chinangwa chekushandisa katatu soldering yemonolithic crystals, saka nepo 96-layer dhizaini inosanganisira iyo yakatwasuka makristasi maviri-48-layer, iyo 144-layer tekinoroji ichave yakavakirwa pamakumi manomwe neshanu-layer. "semi-akapedza zvigadzirwa".
Pamwe chete nekuwedzera kwenhamba yezvikamu muQLC 3D NAND makristasi, vagadziri veIntel havasati vafunga kuwedzera huwandu hwemakristasi pachavo. Zvichienderana ne96- uye 144-layer tekinoroji, iwo akafanana terabit makristasi anozogadzirwa sechizvarwa chekutanga 64-layer QLC 3D NAND. Izvi zvinokonzerwa nechishuwo chekupa SSDs zvichibva pairi nedanho rinogamuchirwa rekuita. Iwo ekutanga maSSD ekushandisa 144-layer memory ichave Arbordale + server madhiraivha.
