SK Hynix amalitela imepụta ibe nchekwa 96-layer 4 Tbit 1D QLC NAND. Ka ọ dị ugbu a, anyị amalitela ibugara ndị nrụpụta ihe nlele nke ibe ndị a maka draịva steeti siri ike. Nke a pụtara na ọ dịghị ọtụtụ oge fọdụrụ tupu uka mmepụta nke ndị a ibe, yana draịva dabeere na ha.
Iji malite, ka anyị cheta na 4D NAND bụ aha ahịa maka ebe nchekwa 3D NAND gbanwere ntakịrị. Ụlọ ọrụ SK Hynix kpebiri iji aha a n'ihi na na microcircuits ya, sekit dị n'akụkụ nke na-achịkwa usoro nke mkpụrụ ndụ adịghị n'akụkụ sel, kama a na-ebugharị n'okpuru ha (Periphery Under Cell, PUC). Ọ bụ ihe na-adọrọ mmasị na ndị na-emepụta ihe ndị ọzọ nwekwara ngwọta yiri nke ahụ, mana ha anaghị eji aha dị elu "4D NAND", ma jiri obi umeala nọgide na-akpọ ebe nchekwa ha "3D NAND".
Dị ka onye nrụpụta si kwuo, ịkwaga akụkụ dị n'okpuru sel emeela ka o kwe omume ibelata mpaghara ibe ahụ ihe karịrị 10% ma e jiri ya tụnyere ibe 3D QLC NAND. Nke a, jikọtara ya na nhazi 96-layer, na-abawanye njupụta data nchekwa. Ọ bụ ezie na, dịka ị maara, ebe nchekwa QLC adịlarị nke ukwuu n'ihi nchekwa nke ozi nkeji anọ na cell.
Ugbu a SK Hynix amalitela ịnye 4 Tbit 1D QLC NAND ibe n'aka ndị nrụpụta dị iche iche maka nnwale na imepụta draịva na-esote dabere na ha. Mana n'otu oge ahụ, ya onwe ya na-arụkwa ọrụ na SSD dabere na ibe ebe nchekwa ndị a. Ụlọ ọrụ ahụ na-arụ ọrụ na njikwa nke ya, ma na-emepụtakwa ntọala ngwanrọ maka ngwọta ya, nke ọ na-ezube ịnyefe n'ahịa ndị ahịa. SK Hynix na-ezube ịhapụ SSD nke ya dabere na 4D QLC NAND n'afọ na-abịa.
