SK Hynix ya fara samar da 96-Layer 4 Tbit 1D QLC NAND kwakwalwan ƙwaƙwalwar ajiya. A halin yanzu, mun fara isar da samfuran waɗannan kwakwalwan kwamfuta zuwa manyan masu haɓaka masu sarrafawa don tuƙi mai ƙarfi. Wannan yana nufin cewa babu sauran lokaci da yawa kafin yawan samar da waɗannan kwakwalwan kwamfuta, da kuma tuƙi akan su.
Don farawa da, bari mu tuna cewa 4D NAND shine sunan talla don ƙwaƙwalwar 3D NAND da aka ɗan gyara. Kamfanin SK Hynix ya yanke shawarar yin amfani da wannan sunan saboda a cikin microcircuits na kewayen kewayen da ke sarrafa tsararrun sel ba sa kusa da sel, amma ana motsa su a ƙarƙashinsu (Periphery Under Cell, PUC). Yana da ban sha'awa cewa sauran masana'antun kuma suna da irin wannan mafita, amma ba sa amfani da babbar sunan "4D NAND", amma cikin ladabi suna ci gaba da kiran ƙwaƙwalwar su "3D NAND".
A cewar masana'anta, motsa abubuwan da ke ƙarƙashin sel ya ba da damar rage yankin kwakwalwan kwamfuta fiye da 10% idan aka kwatanta da kwakwalwan kwamfuta na 3D QLC NAND na gargajiya. Wannan, haɗe tare da shimfidar layi na 96, yana ƙara ƙara yawan adadin bayanai. Ko da yake, kamar yadda kuka sani, ƙwaƙwalwar QLC ta riga ta yi yawa sosai saboda ajiyar bayanai guda huɗu a cikin tantanin halitta.
Yanzu SK Hynix ya fara samar da kwakwalwan kwamfuta na 4 Tbit 1D QLC NAND ga masana'antun daban-daban don gwaji da ƙirƙirar fayafai na gaba dangane da su. Amma a lokaci guda, ita da kanta tana aiki akan SSDs dangane da waɗannan kwakwalwan ƙwaƙwalwar ajiya. Kamfanin yana aiki da nasa na'ura mai sarrafa kansa, kuma yana haɓaka tushen software don mafita, wanda yake shirin isar da shi ga kasuwar masu amfani. SK Hynix yana shirin sakin nasa SSDs dangane da 4D QLC NAND shekara mai zuwa.
