Ndị China ga-amalite inwe mmetụta pụtara ìhè na ahịa NAND n'afọ ọzọ

Dịka anyị kwugoro ugboro ugboro, mmepụta oke nke 64-layer 3D NAND ebe nchekwa ga-amalite na China na njedebe nke afọ a. Onye na-emepụta ebe nchekwa Yangtze Memory Technologies (YMTC) na nhazi nne na nna ya, Tsinghua Unigroup, ekwuola maka nke a ihe karịrị otu ugboro ma ọ bụ ugboro abụọ. Site na data na-akwadoghị, nnukwu mmepụta nke 64-layer 128-Gbit YMTC ibe nwere ike ịmalite na nkeji nke atọ. Nkesa ihe atụ nke ebe nchekwa dị otú ahụ, dokwuo anya Ndị nyocha DRAMeXchange sitere na TrendForce, ụlọ ọrụ ahụ malitere na nkeji mbụ nke afọ a. Ugbu a ụlọ ọrụ Wuhan, ebe YMTC mbụ 300mm silicon wafer na-emepụta ihe dị na ya, na-emepụta oke 32-layer 64Gbit 3D NAND.

Ndị na-emepụta China amaliteghị mmepụta nke 32-layer 3D NAND ma lekwasị anya na ebumnuche ịkwaga na mmepụta nke 128-Gbit 64-Layer NAND flash ma ọ bụ obere asọmpi ozugbo enwere ike. Nke a ga-emeghe ụzọ mmepụta mpịakọta na mbụ YMTC osisi na-esote afọ na larịị nke 60 puku 300 mm wafers kwa ọnwa. Enweghị ike iji mpịakọta ndị dị otú ahụ tụnyere ike nke Samsung, SK Hynix ma ọ bụ Micron, nke ọ bụla na-eme ihe ruru 200 puku substrates kwa ọnwa. Ma mpịakọta ndị a nke Chinese 3D NAND nwere ike ime ka ahịa ahịa na-adịghị mma maka ndị na-emepụta ihe na, dị ka DRAMeXchange nwere obi ike, ha ga-enwe mmetụta dị ukwuu na ahịa maka ebe nchekwa NAND na ngwaahịa dabere na ebe nchekwa dị otú ahụ n'afọ ọzọ.

Site n'ụzọ, ndị asọmpi nwere oge n'onwe ha na-enye YMTC mmalite mmalite. N'afọ a, iji kwụsị mmepụta oke, ndị isi ahịa na-ebelata itinye ego na mmepe nke ahịrị ụlọ ọrụ na ọbụna akụkụ - site na 5-15% - ibelata olu nke mmepụta 3D NAND ibe ugbu a. Nke a pụtara na ngbanwe na mmepụta oke nke 92-96-layer 3D NAND kama 64-72-layer ga-akwụsịlata ma gbuo oge ruo n'afọ ọzọ. Nke a ga-egbukwa oge mgbanwe nke ndị isi na ntọhapụ nke 128-layer 3D NAND. YMTC, n'ụzọ megidere nke ahụ, ọ bụghị naanị na ọ naghị ebelata itinye ego, ọ ga-ama ụma wụpụ ntọhapụ nke 96-layer 3D NAND wee malite ozugbo imepụta ebe nchekwa 128-Layer n'afọ ọzọ. Ọganihu teknụzụ a ga-ebelata ohere dị n'etiti ndị China na ndị asọmpi America na South Korea ruo otu afọ ma ọ bụ abụọ, nke na-anaghịkwa eme nke ọma maka ndị agha ụlọ ọrụ.
