SK Hynix yayamba kupanga 96-wosanjikiza 4 Tbit 1D QLC NAND memory chips. Pakadali pano, tayamba kupereka zitsanzo za tchipisi tating'onoting'ono kwa opanga owongolera ma drive olimba. Izi zikutanthauza kuti palibe nthawi yochuluka yomwe yatsala kuti tchipisi tambiri tipangidwe, komanso ma drive otengera iwo.
Poyamba, tiyeni tikumbukire kuti 4D NAND ndi dzina lamalonda la kukumbukira kosinthidwa pang'ono kwa 3D NAND. Kampani ya SK Hynix idaganiza zogwiritsa ntchito dzinali chifukwa mu ma microcircuits ake mabwalo ozungulira omwe amawongolera kuchuluka kwa ma cell sapezeka pafupi ndi ma cell, koma amasunthidwa pansi pawo (Periphery Under Cell, PUC). Ndizosangalatsa kuti opanga ena nawonso ali ndi mayankho ofanana, koma sagwiritsa ntchito dzina lokweza "4D NAND", koma modzichepetsa amapitiliza kuyitana kukumbukira kwawo "3D NAND".
Malinga ndi wopanga, kusuntha zotumphukira pansi pa maselo kwapangitsa kuti zichepetse gawo la tchipisi ndi 10% poyerekeza ndi tchipisi tating'ono ta 3D QLC NAND. Izi, kuphatikiza ndi masanjidwe a 96-wosanjikiza, zimawonjezeranso kachulukidwe kosungirako deta. Ngakhale, monga mukudziwa, kukumbukira kwa QLC kuli kale kolimba kwambiri chifukwa chosungirako zidziwitso zinayi mu cell.
Tsopano SK Hynix yayamba kupereka tchipisi ta 4 Tbit 1D QLC NAND kwa opanga osiyanasiyana kuti ayesere ndikukhazikitsanso ma drive otengera iwo. Koma nthawi yomweyo, iyenso akugwira ntchito pa ma SSD potengera tchipisi tokumbukira izi. Kampaniyo ikugwira ntchito payokha, ndipo ikupanganso maziko a mapulogalamu a mayankho ake, omwe akukonzekera kupereka ku msika wa ogula. SK Hynix ikukonzekera kumasula ma SSD ake kutengera 4D QLC NAND chaka chamawa.
