Namuhla ekuseni eSeoul, eSouth Korea, i-Intel ibambe umcimbi othi “Memory and Storage Day 2019” onikezelwe ezinhlelweni zesikhathi esizayo kumemori kanye nemakethe ye-solid-state drive. Lapho, abamele inkampani bakhulume ngamamodeli esikhathi esizayo we-Optane, inqubekelaphambili ekuthuthukisweni kwe-XNUMX-bit PLC NAND (Penta Level Cell) nobunye ubuchwepheshe obuthembisayo ehlela ukuyikhuthaza eminyakeni ezayo. I-Intel iphinde yakhuluma ngesifiso sayo sokwethula i-RAM engaguquguquki kumakhompyutha edeskithophu esikhathini eside futhi mayelana namamodeli amasha ama-SSD ajwayelekile ale ngxenye.
Ingxenye ebingalindelekile kakhulu yesethulo se-Intel mayelana nentuthuko eqhubekayo kwakuyindaba emayelana ne-PLC NAND - uhlobo oluminyene nakakhulu lwenkumbulo ye-flash. Le nkampani igcizelela ukuthi eminyakeni emibili edlule, inani eliphelele ledatha ekhiqizwa emhlabeni liye laphindeka kabili, ngakho-ke amadrayivu asekelwe ku-32-bit QLC NAND akusabonakali njengesixazululo esihle kule nkinga - imboni idinga izinketho ezithile eziphakeme. ukuminyana kwesitoreji. Okukhiphayo kufanele kube inkumbulo ekhanyayo ye-Penta-Level Cell (PLC), iseli ngayinye egcina amabhithi amahlanu edatha ngesikhathi esisodwa. Ngakho-ke, isigaba sezinhlobo zememori ye-flash maduze sizobukeka njenge-SLC-MLC-TLC-QLC-PLC. I-PLC NAND entsha izokwazi ukugcina idatha ephindwe kahlanu uma iqhathaniswa ne-SLC, kodwa, kunjalo, ngokusebenza okuphansi nokuthembeka, njengoba isilawuli kuzodingeka sihlukanise phakathi kwezifunda ezingu-XNUMX ezihlukene zokukhokha zeseli ukuze abhale futhi afunde izingcezu ezinhlanu. .
Kuyaqapheleka ukuthi i-Intel ayiyedwa emzamweni wayo wokwenza inkumbulo ye-flash eminyene. U-Toshiba uphinde wakhuluma ngezinhlelo zokudala i-PLC NAND ngesikhathi seNgqungquthela Yenkumbulo Ye-Flash eyayingo-August. Kodwa-ke, ubuchwepheshe be-Intel buhluke kakhulu: inkampani isebenzisa amaseli enkumbulo esango elintantayo, kuyilapho imiklamo kaToshiba yakhelwe eduze kwamaseli asekelwe kumgibe. Ngokukhula komthamo wesitoreji solwazi, isango elintantayo libonakala liyisixazululo esingcono kakhulu, njengoba linciphisa ithonya elilinganayo nokugeleza kwezindleko kumaseli futhi lenze kube nokwenzeka ukufunda idatha ngamaphutha ambalwa. Ngamanye amazwi, idizayini ye-Intel ifaneleka kangcono ekukhuleni kwabantu, okuqinisekiswa yimiphumela yokuhlolwa kwe-QLC NAND etholakalayo kwezohwebo eyenziwe kusetshenziswa ubuchwepheshe obuhlukahlukene. Ukuhlola okunjalo kubonisa ukuthi ukuwohloka kwedatha kumaseli enkumbulo ye-QLC asekelwe esangweni elintantayo kwenzeka kancane kancane izikhathi ezimbili kuya kwezintathu kunamaseli e-QLC NAND anomgibe wokushaja.
Ngokumelene nalesi sizinda, ulwazi uMcron anquma ukwabelana ngalo nokuthuthukiswa kwenkumbulo ye-flash ne-Intel, phakathi kwezinye izinto, ngenxa yesifiso sokushintshela ekusebenziseni amaseli omgibe wokushaja, lubukeka luthakazelisa kakhulu. I-Intel ihlala izibophezele kubuchwepheshe bokuqala futhi iyisebenzisa ngokuhlelekile kuzo zonke izixazululo ezintsha.
Ngokungeziwe ku-PLC NAND, esathuthukiswa, i-Intel ihlose ukukhulisa ukuminyana kokugcinwa kolwazi kwimemori ye-flash ngokusebenzisa obunye, ubuchwepheshe obuthengekayo. Ikakhulukazi, inkampani iqinisekise uguquko oluseduze lokukhiqizwa ngobuningi be-96-layer QLC 3D NAND: izosetshenziswa kudrayivu entsha yabathengi. .
Lokhu kuzolandelwa wukufunda kahle ukukhiqizwa kwe-144-layer QLC 3D NAND - izoshaya amadrayivu okukhiqiza ngonyaka ozayo. Kuyathakazelisa ukuthi i-Intel kuze kube manje inqabele noma iyiphi inhloso yokusebenzisa ukuthengiswa okuphindwe kathathu kwamakristalu e-monolithic, ngakho-ke ngenkathi umklamo we-96-layer uhlanganisa ukuhlanganiswa okuqondile kwamakristalu amabili-layer angama-48, ubuchwepheshe be-144-layer ngokusobala buzosekelwe ku-72-layer. "imikhiqizo eseqediwe".
Kanye nokwenyuka kwenani lezendlalelo kumakristalu e-QLC 3D NAND, abathuthukisi be-Intel abakahlosile ukukhulisa umthamo wamakristalu ngokwawo. Ngokusekelwe kubuchwepheshe bezendlalelo ezingu-96- kanye no-144, amakristalu e-terabit afanayo azokhiqizwa njengesizukulwane sokuqala esingu-64-layer QLC 3D NAND. Lokhu kungenxa yesifiso sokuhlinzeka ngama-SSD ngokusekelwe kuwo ngezinga elamukelekayo lokusebenza. Ama-SSD okuqala azosebenzisa inkumbulo yezendlalelo eziyi-144 azoba amadrayivu e-Arbordale+ server.
