Pambuyo pa Chia hard drive mining fever yachepa, theSSDmitengo ya hard drive yomwe idakwera kwambiri mu Meyi yabwereranso kumagulu abwinobwino, ndi1TBmitengo nthawi zambiri mkati mwa madola chikwi.Komabe, uthenga wabwino siutali.SSDhard disk posachedwa akumana ndi vuto lina, nthawi ino kuchepa kwa tchipisi tating'onoting'ono, 28nm mankhwala amanjenje kwambiri, ndizotheka kuyendetsa mtengo waSSD.
Nkhani kuchokera ku chain chain inanena kuti kuchepa kwa NAND flash memory master chip kupanga kupitilira mpaka kumapeto kwa 2022, kusiyana kukuyembekezeka kukwera mpaka 20-30%, makamaka kupezeka kwa 28nm okhwima process master chip ndi zolimba kwambiri.
SSDflash main control chip sichifunikira njira yomaliza kwambiri, pali zida zambiri za 40nm process main control chip zomwe zikugwiritsidwa ntchito, zapamwamba kwambiri.PCIe 4.0Kuwongolera kwakukulu kumagwiritsidwa ntchito pa 16nm, kuwongolera kwakukulu kwa PCIe 5.0 kudzagwiritsanso ntchito 7nm, komaPCIe 3.0, mawonekedwe a SATA main control chip akadali olamulidwa ndi 28nm, pambuyo pake, mtengo, magwiridwe antchito, kugwiritsa ntchito mphamvu ndikoyenera kwambiri.
Global 28nm foundry mphamvu makamaka anaikira TSMC, UMC ndi SMIC opanga atatu akuluakulu, kuphatikizapo TSMC kukonzekera mwakhama kukulitsa ndondomeko okhwima 28nm mphamvu, akuyembekezeka kwa zaka 2-3 zikubwerazi, 28nm okwana mphamvu akuyembekezeka kukulitsa 100,000 kuti 150,000 zidutswa pamwezi.
UMC inalengeza mu May chaka chino ndondomeko ya ndalama zokwana madola 3.6 biliyoni zomwe zidzagwiritsidwe ntchito kuonjezera 28nm process chip kupanga.
SMIC ikukulitsanso njira yake ya 28nm, pokhazikitsa mapulojekiti angapo okhwima ku Beijing ndi Shenzhen ndi ndalama zokwana 65.3 biliyoni, kapena pafupifupi $10 biliyoni.
SK Hynix ikuyang'ananso kwambiri pakupanga phindu la kukumbukira kwa NAND flash, kukonzekera kukulitsa malonda a 128-layer-based based solution solutions ndi mabizinesi apamwamba.SSDs mgawo lachitatu ndikukwaniritsa kupanga kwakukulu kwa 176-layer NAND flash memory mu theka lachiwiri la chaka chino.
Kusanthula kwamakampani, m'mbuyomu, kotala ya 2 ndi nyengo yanthawi yayitali yamafakitale okhudzana ndi NAND, koma chaka chino zinthu nzosiyana kwambiri, osati kuchuluka kokha komwe kumakhala kolimba kwambiri, kutsika kwa mantha akusowa kwazinthu komanso kusungira zinthu zonse mopenga. njira, ndiyeno chochitika chotseka chomera cha Samsung Texas Austin, zomwe zidapangitsa kuti ma NAND aziwongolera ma ICs, kukulitsa kukayikirana kwa kusweka kwa mafakitale, zomwe zimapangitsa kuti 2 kotala kutsika kwa mtsinje kuchuluke, chaka chino Q3, kutumiza kwa NAND Flash. mphamvu idzapitirira kukwera, ndipo mtengo udzapitirira kukwera.
