Kwa China, kupanga kwakukulu kwa owongolera kuti apange ma SSD ndikofunikira monga bungwe lopanga nyumba za NAND flash ndi kukumbukira kwa DRAM. Kupanga kochepa kwa tchipisi ta 32-layer 3D NAND ndi DDR4 kwayamba kale mdziko muno. Nanga bwanji owongolera?
Malinga ndi malowa , ku China, pafupifupi makampani khumi akupanga owongolera a SSD. Onse amagwiritsa ntchito ma cores kapena mapangidwe a ARM (ma seti a malangizo). Koma kampani ina idakwanitsa kudabwa: posachedwa wopanga dziko kuchokera ku China adapereka olamulira kutengera kamangidwe kake kaku China kakang'ono, Godson.
Zomangamanga za Godson kapena ma cores zidakhala maziko a ma processor a Loongson omwe adadziwika kwambiri kulibe. Zomangamanga za Godson zimadalira malangizo a MIPS ndipo, kwenikweni, sizoyipa kwa oyang'anira SSD kuposa zomangamanga za ARM. The Godson IP controller idapangidwa ndi kampani yaku China Guokewei. Awa ndi mayankho a GK2302 okhala ndi mawonekedwe a SATA 6 Gb/s komanso kuthamanga kwa ntchito mpaka 500 MB/s.
Malinga ndi kampaniyo, wolamulira wa GK2302 pa IP Godson ndiwopanga 15% kuposa momwe adapangidwira kale pamagulu a ARM (GK2301) ndipo amagwiritsa ntchito mphamvu zochepera 6,5%. Palibe chidziwitso china chokhudza GK2302 pano. Kuti mumve zambiri, GK2301 imathandizira njira zinayi zokumbukira ndi kukonza zolakwika za LDPC ndikukulolani kuti mupange ma SSD okhala ndi mphamvu yofikira 4 TB (mpaka tchipisi 32 NAND MLC/TLC/QLC). Zothandizira: ONFI 3.0/Toggle 2.0, komanso SM2/3/4 (mtundu wadziko) ndi SHA-256/AES-256 encryption. Chinachake chofananacho chingayembekezeredwe kuchokera kwa wolamulira watsopano.
Mawu ochepa okhudza kampani ya Guokewei. Idakhazikitsidwa mu 2008, ngakhale idalowa muzogulitsa zachitetezo mu 2017. Kampaniyo imagwira ntchito popanga tchipisi ta mabokosi apamwamba, makina osungira ma data, owongolera masensa ndi zinthu zolumikizidwa ndi intaneti. Mu 2018, malonda a Guokewei anali pafupifupi $ 57,68 miliyoni.
