Posachedwapa, pachiwonetsero chachisanu ndi chiwiri cha China Electronic Information Expo (CITE2019) ku Shenzhen, SSD P8260 yoyamba yolimba, yosonkhanitsidwa kuchokera ku zigawo zaku China, idawonetsedwa pamalo a Tsinghua Unigroup. Iyi ndi SSD-grade-grade SSD momwe olamulira, DRAM buffer ndi 3D NAND array adapangidwa ndikupangidwa ku China. Chabwino, China yatenganso gawo lina ndipo ikuyembekeza kutsata njira iyi kuti ikwaniritse kudziyimira pawokha pokumbukira kupanga zakunja.
Aliyense amene amatsatira nkhani za chitukuko ndi kupanga 3D NAND kukumbukira ku China akudziwa kuti kupanga kung'anima kukumbukira chips ikuchitika ndi ankapitabe limodzi ndi Tsinghua, Yangtze River Storage Technology (YMTC). Ma drive a P8260 amakhala ndi zinthu zoyamba za YMTC 32-wosanjikiza 3Gb 64D NAND. Kumapeto kwa chaka, wopanga ayamba kupanga tchipisi ta 128 Gbit 64-wosanjikiza 3D NAND, zomwe zipangitsa kuti YMTC ipezeke pamalonda - pomwe kupanga kukusokonekera.
Kukumbukira kwa DRAM kwa buffer ya SSD kumapangidwa ndi wothandizira Tsinghua Guoxin Micro. Kukula kwa bafa sikunanenedwe. Wowongolerayo adapangidwa ndi kampani yaku China Beijing Ziguang Storage Technology, yomwe imagwirizananso ndi Tsinghua Unigroup.
Wolamulira wa P8260 ndi kuyendetsa amathandizira NVMe 1.2.1 protocol ndi PCI Express 3.0 x4 mawonekedwe. Thandizo la mayendedwe 16 okumbukira limalengezedwa, lomwe limalonjeza bandwidth yayikulu, koma deta yeniyeni pakuchita kwa P8260 sinafotokozedwe. Kuti mugwire ntchito ndi buffer ya DRAM, purosesa ili ndi chowongolera kukumbukira chanjira ziwiri zokhala ndi basi ya 40-bit ndi thandizo la ECC. Mitundu iwiri ya SSD P8260 imaperekedwa: yokhala ndi 1 ndi 2 TB mu mawonekedwe a PCIe khadi ndi U.2 drive.
Kuphatikiza pa ma drive a P8260, wopanga adawonetsanso ma SSD ogula a mabanja a P100 ndi S100. Komabe, kampaniyo imagula kukumbukira kwa 3D NAND kwamitundu iyi kuchokera kwa anzawo. Mmodzi wotere, mwachitsanzo, ndi Intel.
