SK Hynix yatanga kugadzirwa kwe96-layer 4 Tbit 1D QLC NAND memory chips. Parizvino, takatanga kuendesa samples dzemachipi aya kune makuru madhizaini evatongi veakasimba-nyika madhiraivha. Izvi zvinoreva kuti hapachina nguva yakawanda yasara pamberi pekugadzirwa kwakawanda kwemachipi aya, pamwe nemadhiraivha akavakirwa pazviri.
Kutanga, ngatiyeukei kuti 4D NAND izita rekushambadzira rekugadzirisa zvishoma 3D NAND memory. Kambani yeSK Hynix yakafunga kushandisa zita iri nekuti mumamicrocircuits ayo maseketi ekutenderera anodzora ruzhinji rwemasero haawanikwe padyo nemasero, asi anofambiswa pasi pawo (Periphery Under Cell, PUC). Zvinonakidza kuti vamwe vagadziri vanewo mhinduro dzakafanana, asi ivo havashandise zita repamusoro "4D NAND", asi nekuzvininipisa vanoramba vachidana ndangariro yavo "3D NAND".
Sekureva kwemugadziri, kufambisa maperipherals pasi pemaseru kwaita kuti zvikwanisike kudzikisa nzvimbo yemachipisi neinopfuura gumi% zvichienzaniswa neyekare 10D QLC NAND chips. Izvi, zvakasanganiswa ne3-layer dhizaini, inowedzera kuwedzera data rekuchengetedza density. Kunyangwe, sekuziva kwamunoita, QLC ndangariro yatove denda zvakanyanya nekuda kwekuchengetwa kwemabhiti mana eruzivo muchitokisi.
Iye zvino SK Hynix yatanga kupa 4 Tbit 1D QLC NAND machipi kune vakasiyana vagadziri kuti vaedze uye nekuzotevera kusikwa kwemadhiraivha kwakavakirwa pavari. Asi panguva imwecheteyo, iye pachake ari kushandawo paSSDs zvichibva pane aya machipisi. Iyo kambani iri kushanda pachayo controller, uye zvakare iri kugadzira hwaro hwesoftware yemhinduro dzayo, iyo yainoronga kuendesa kumusika wevatengi. SK Hynix inoronga kuburitsa maSSD ayo akavakirwa pa4D QLC NAND gore rinouya.
