Kutulutsa kwatsopano kwa atolankhani kuchokera ku Samsung Electronics kuti yayamba kupanga zochuluka za 3D NAND yokhala ndi zigawo zopitilira 100. Kukonzekera kwapamwamba kwambiri kumalola tchipisi okhala ndi zigawo 136, zomwe zikuwonetsa gawo latsopano panjira yopita ku kukumbukira kowala kwa 3D NAND flash. Kusowa kwa kasinthidwe kachikumbutso kowoneka bwino kukuwonetsa kuti chip chokhala ndi zigawo zopitilira 100 chimasonkhanitsidwa kuchokera pawiri kapena, mwina, atatu monolithic 3D NAND amafa (mwachitsanzo, 48-wosanjikiza). Panthawi yopangira makristasi, zigawo zina zam'malire zimawonongeka, ndipo izi zimapangitsa kuti zikhale zosatheka kuwonetsa molondola kuchuluka kwa zigawo za kristalo, kuti Samsung isatsutsidwe pambuyo pake.
Komabe, Samsung imaumirira pamabowo apadera a tchanelo, omwe amatsegula mwayi woboola mu makulidwe a kapangidwe ka monolithic ndikulumikiza zopingasa zokumbukira kung'anima mu memory chip imodzi. Zopangira 100 zoyambirira zinali tchipisi ta 3D NAND TLC zokhala ndi mphamvu ya 256 Gbit. Kampaniyo iyamba kupanga tchipisi cha 512-Gbit chokhala ndi zigawo 100 (+) kugwa uku.
Kukana kumasula kukumbukira kwakukulu kumatsimikiziridwa ndi mfundo (mwina) kuti mlingo wa zolakwika pamene mukutulutsa zatsopano ndizosavuta kuzilamulira pankhani ya kukumbukira mphamvu zochepa. Mwa "kuchulukitsa chiwerengero cha pansi," Samsung inatha kupanga chip ndi malo ang'onoang'ono popanda kutaya mphamvu. Komanso, chip wakhala chosavuta m'njira zina, popeza tsopano m'malo 930 miliyoni ofukula mabowo mu monolith, ndi zokwanira etch 670 miliyoni mabowo. Malinga ndi Samsung, izi zafewetsa ndikufupikitsa zopangira ndikupangitsa kuti chiwonjezeko cha 20% pakugwira ntchito, kutanthauza kutsika mtengo.
Kutengera kukumbukira kwa magawo 100, Samsung idayamba kupanga 256 GB SSD yokhala ndi mawonekedwe a SATA. Zogulitsazo zidzaperekedwa ku PC OEMs. Palibe kukayika kuti Samsung posachedwa ibweretsa ma drive odalirika komanso otsika mtengo kwambiri.
Kusintha kwa mawonekedwe a 100-wosanjikiza sikunatikakamize kupereka nsembe kapena kugwiritsa ntchito mphamvu. 256 Gbit 3D NAND TLC yatsopano inali 10% mwachangu kuposa kukumbukira-kusanjikiza 96. Mapangidwe abwino amagetsi owongolera a chip adapangitsa kuti zitheke kusunga kuchuluka kwa kusamutsa kwa data polemba pansi pa 450 μs, komanso powerenga pansi pa 45 μs. Panthawi imodzimodziyo, kumwa kunachepetsedwa ndi 15%. Chochititsa chidwi kwambiri ndichakuti kutengera 100-wosanjikiza 3D NAND, kampaniyo ikulonjeza kumasula 300-wosanjikiza 3D NAND kenako, kungophatikiza makhiristo atatu osanjikiza 100. Ngati Samsung ingayambe kupanga 300-wosanjikiza 3D NAND chaka chamawa, kudzakhala kukankha kowawa kwa omwe akupikisana nawo. flash memory industry.
