Mtundu wachiwiri waukadaulo wa Xtacking wakonzedwa ku China 3D NAND

Kodi lipoti Mabungwe ofalitsa nkhani ku China, Yangtze Memory Technologies (YMTC) akonza mtundu wachiwiri waukadaulo wake wa Xtacking kuti akwaniritse kupanga kukumbukira kwamitundu yambiri ya 3D NAND flash. Tekinoloje ya Xtacking, tikukumbukira, idaperekedwa pamwambo wapachaka wa Flash Memory Summit mu Ogasiti chaka chatha ndipo idalandiranso mphotho m'gulu la "Kuyambira kwatsopano kwambiri pankhani ya kukumbukira kwa flash."

Zachidziwikire, kuyitanitsa bizinesi yokhala ndi bajeti ya madola mabiliyoni ambiri kuti iyambike ndikuchepetsa kampaniyo, koma, tiyeni tinene zoona, YMTC simapangabe zinthu zambiri. Kampaniyo isamukira kuzinthu zambiri zamalonda za 3D NAND chakumapeto kwa chaka chino pomwe ikhazikitsa kukumbukira kwa 128-Gbit 64-wosanjikiza, zomwe, mwanjira, zidzathandizidwa ndiukadaulo womwewo wa Xtacking.

Motsatira malipoti aposachedwa, posachedwa pamwambo wa GSA Memory +, Yangtze Memory CTO Tang Jiang adavomereza kuti ukadaulo wa Xtacking 2.0 udzaperekedwa mu Ogasiti. Tsoka ilo, mutu waukadaulo wa kampaniyo sanafotokoze zambiri zachitukuko chatsopanocho, chifukwa chake tiyenera kuyembekezera mpaka Ogasiti. Monga momwe zimasonyezera m'mbuyomu, kampaniyo imasunga chinsinsi mpaka kumapeto komanso isanayambike Flash Memory Summit 2019, sitingathe kuphunzira chilichonse chosangalatsa chokhudza Xtacking 2.0.

Ponena za ukadaulo wa Xtacking womwe, cholinga chake chinali mfundo zitatu: kupereka chikoka champhamvu pakupanga 3D NAND ndi zinthu zochokera pa izo. Awa ndi liwiro la mawonekedwe a flash memory chips, kuwonjezeka kwa kachulukidwe kujambula komanso kuthamanga kwa kubweretsa zinthu zatsopano pamsika. Ukadaulo wa Xtacking umakupatsani mwayi woti muwonjezere kusinthana ndi ma memory array mu tchipisi ta 3D NAND kuchokera pa 1–1,4 Gbit/s (ONFi 4.1 ndi ToggleDDR interface) mpaka 3 Gbit/s. Pamene mphamvu ya tchipisi ikukula, zofunikira zosinthira liwiro zidzawonjezeka, ndipo aku China akuyembekeza kukhala oyamba kuchita bwino m'derali.

Palinso chopinga china pakukulitsa kachulukidwe kajambulidwe - kupezeka kwa 3D NAND chip osati kungokumbukira, komanso kuwongolera zotumphukira ndi mabwalo amagetsi. Mabwalowa amachotsa 20% mpaka 30% ya malo omwe angagwiritsidwe ntchito pokumbukira, komanso 128% ya chip pamwamba pa tchipisi ta 50-Gbit. Pankhani yaukadaulo wa Xtacking, gulu lokumbukira limapangidwa pa chip chake, ndipo mabwalo owongolera amapangidwa pa china. Crystal imadzipereka kwathunthu ku ma cell a kukumbukira, ndipo mabwalo owongolera pagawo lomaliza la msonkhano wa chip amamangiriridwa ku kristalo ndi kukumbukira.

Kupanga kosiyana ndi kusonkhana kotsatira kumathandizanso kuti pakhale chitukuko chofulumira cha tchipisi tokumbukira ndi zinthu zomwe zimasonkhanitsidwa ngati njerwa ndikuphatikiza koyenera. Njirayi imatithandiza kuchepetsa kukula kwa tchipisi tomwe timakumbukira ndi miyezi itatu pa nthawi yachitukuko ya miyezi 3 mpaka 12. Kusinthasintha kwakukulu kumatanthauza chidwi chamakasitomala, chomwe wopanga wachinyamata waku China amafunikira ngati mpweya.
