MaChinese achatanga kuve nesimba rinoonekwa pamusika weNAND gore rinouya

Sezvatakadzokorora kutaura, kugadzirwa kwakawanda kwe64-layer 3D NAND ndangariro kuchatanga muChina mukupera kwegore rino. Memory inogadzira Yangtze Memory Technologies (YMTC) uye chimiro chayo chevabereki, Tsinghua Unigroup, vakataura nezve izvi kanopfuura kamwe kana kaviri. By unofficial data, kugadzirwa kwakawanda kwe64-layer 128-Gbit YMTC chips inogona kutanga muchikamu chechitatu. Kugoverwa kwemasamples endangariro dzakadaro, jekesa DRAMeXchange vanoongorora kubva kuTrendForce, kambani yakatanga mukota yekutanga yegore rino. Ikozvino nzvimbo yeWuhan, uko YMTC yekutanga 300mm silicon wafer processing plant iripo, iri kuburitsa huwandu hushoma hwe32-layer 64Gbit 3D NAND.

Mugadziri weChinese haana kutanga kugadzirwa kwakawanda kwe32-layer 3D NAND uye akatarisa pachinangwa chekufambisa kune kugadzirwa kweakawanda kana mashoma anokwikwidza 128-Gbit 64-layer NAND flash nekukurumidza. Izvi zvichavhura nzira yekugadzira mavhoriyamu payekutanga YMTC chirimwa gore rinouya pamwero we60 zviuru 300 mm wafers pamwedzi. Mavhoriyamu akadaro haakwanise kuenzaniswa nekugona kweSamsung, SK Hynix kana Micron, iyo yega yega inosvika mazana maviri ezviuru substrates pamwedzi. Asi aya mavhoriyamu eChinese 200D NAND anogona kuwedzera maitiro asina kunaka emusika kune vagadziri uye, seDRAMeXchange ine chivimbo, ivo vanozove nekukanganisa kwakakosha pamusika weNAND ndangariro uye zvigadzirwa zvinoenderana nendangariro dzakadaro gore rinouya.

Nenzira, vakwikwidzi vane ruzivo pachavo vanopa YMTC kutanga. Gore rino, kumisa kuwandisa, vatungamiriri vemusika vari kuderedza mari mukusimudzira mitsara yeindasitiri uye kunyange zvishoma - ne5-15% - kuderedza huwandu hwekugadzirwa kwazvino kwe3D NAND chips. Izvi zvinoreva kuti shanduko yekugadzirwa kwehuwandu hwe92-96-layer 3D NAND panzvimbo ye64-72-layer ichadzikiswa uye inonokerwa kusvika gore rinouya. Izvi zvichanonotsawo shanduko yevatungamiriri kuburitswa kwe128-layer 3D NAND. YMTC, zvakapesana, haingodzikisi mari, inosvetuka nemaune kuburitswa kwe96-layer 3D NAND uye nekukasika gadzira 128-layer memory gore rinouya. Kubudirira kwetekinoroji uku kunoderedza musiyano uripo pakati pevaChinese nevakwikwidzi vavo vekuAmerican neSouth Korea kusvika gore kana maviri, izvo zvakare zvisingaenderane nemaindasitiri veterans.
