I-Western Digital kunye no-Toshiba bacebise imemori edanyazayo enamasuntswana amahlanu edatha ebhalwe kwiseli nganye

Inyathelo elinye ukuya phambili, amanyathelo amabini umva. Ukuba malunga ne-NAND flash cell enamasuntswana ali-16 abhalelwe nganye ungaphupha kuphela, emva koko singakwazi kwaye kufuneka sithethe ngokubhala amasuntswana amahlanu kwiseli. Kwaye bathi. KwiNgqungquthela yeMemori yeFlash ngo-2019, eToshiba thaca Umbono wokukhulula i-5-bit ye-NAND PLC yeseli njengenyathelo elilandelayo emva kokuqonda ukuveliswa kwememori ye-NAND QLC.

Ukutshintshwa kwimemori ye-NAND PLC kuya kwongeza enye i-25% kumthamo we-flash arrays xa kuthelekiswa ne-NAND QLC. Phantse ngaphandle kweblue kunye nemali efanayo, i-256 GB SSD iya kuba yi-320 GB enye. Nangona kunjalo, ukuxhathisa ukunxiba, ukuthembeka kunye nesantya sememori ye-flash kuya kubandezeleka. Oku akunakwenzeka ukuba kumise ishishini. Kuphela nje ukuba ukuqhuba ngememori ye-NAND PLC kuya kuba sentliziyweni yezo zisombululo apho ukubhalwa kwakhona rhoqo kungafuneki, kodwa isantya sokufikelela sibalulekile. Umzekelo, ukurekhoda oovimba. Udlala kumasango afanayo iteknoloji yokurekhoda indawo, xa umculo, iimuvi kunye nezinye iindidi zedatha zirekhodwa ngokungqongqo kwiindawo zabo zememori ezimiselwe kwangaphambili.

Ukumelana nokunxiba okulindelweyo kwememori ye-NAND PLC kuya kuncipha kwitekhnoloji yenkqubo yeklasi ye-10 nm ukusuka kwimijikelo engama-70 yokubhala kwakhona (ukucima) ukuya kwimijikelo engama-35. Kwimemori ye-3D NAND, la manani anokuba phezulu, kuba imveliso yawo isebenzisa iinkqubo ezinkulu zobuchwepheshe. Inani lemijikelezo linokunyuswa ngokwenza abalawuli babe nzima ngakumbi kwiibhloko zokulungisa iimpazamo eziyinkimbinkimbi, kodwa umlawuli uya kuba sele enomsebenzi wokudibanisa kungekhona isibonakaliso senqanaba le-16 kwiseli ye-QLC, kodwa isignali ye-32 kwinqanaba Iseli ye-PLC.

Kufuneka kwakhona uqonde ukuba kuya kubakho indawo encinci yokutshaja (izinga lokurekhoda) kwiseli ye-PLC kuneseli ye-QLC, okanye indawo yeseli yokurekhoda kwinqanaba le-32 kuya kufuneka yandiswe. Ukuba oku akwenziwanga, ukuthembeka kokurekhoda kuya kuncipha okanye umlawuli uya kuba nzima ngakumbi. Ngelizwi, kukho into yokuthetha ngayo. Ukuba umzi-mveliso uthatha isigqibo sokutshintshela kwimemori kunye neseli ye-five-bit, oku akuyi kwenzeka kude kube ngu-2021.
