I kēia kakahiaka ma Seoul, South Korea, ua mālama ʻo Intel i ka hanana "Memory and Storage Day 2019" i hoʻolaʻa ʻia i nā hoʻolālā e hiki mai ana i ka mākeke hoʻomanaʻo a me ka mākeke. Ma laila, kamaʻilio nā ʻelele o ka hui e pili ana i nā hiʻohiʻona Optane e hiki mai ana, ka holomua i ka hoʻomohala ʻana i ka PLC NAND ʻelima-bit (Penta Level Cell) a me nā ʻenehana hoʻohiki ʻē aʻe e hoʻolālā ana e hoʻolaha i nā makahiki e hiki mai ana. Ua ʻōlelo pū ʻo Intel e pili ana i kona makemake e hoʻolauna i ka RAM non-volatile i nā kamepiula papa i ka wā lōʻihi a e pili ana i nā hiʻohiʻona hou o nā SSD maʻamau no kēia māhele.
ʻO ka mea kupanaha loa o ka hōʻike ʻana a Intel i ka hoʻomohala mau ʻana ʻo ia ka kamaʻilio e pili ana iā PLC NAND, kahi ʻano ʻoi aku o ka hoʻomanaʻo flash. Hoʻomaopopo ka ʻoihana i nā makahiki ʻelua i hala iho nei, ua pālua ka nui o ka ʻikepili i hana ʻia ma ka honua, no laila ʻaʻole i ʻike hou ʻia nā drive e pili ana i ʻehā-bit QLC NAND he hopena maikaʻi i kēia pilikia - pono ka ʻoihana i kekahi mau koho me ke kiʻekiʻe. mānoanoa mālama. ʻO ka hoʻopuka ʻana he Penta-Level Cell (PLC) hoʻomanaʻo flash, ʻo kēlā me kēia cell e mālama i ʻelima mau ʻikepili i ka manawa hoʻokahi. No laila, e like koke ka hierarchy o nā ʻano hoʻomanaʻo flash e like me SLC-MLC-TLC-QLC-PLC. Hiki i ka PLC NAND hou ke mālama i ʻelima mau manawa hou aʻe i ka hoʻohālikelike ʻia me SLC, akā, ʻoiaʻiʻo, me ka haʻahaʻa haʻahaʻa a me ka hilinaʻi, no ka mea, pono e hoʻokaʻawale ka mea hoʻoponopono ma waena o 32 mau mokuʻāina like ʻole o ke kelepona e kākau a heluhelu i ʻelima mau ʻāpana. .
He mea pono e hoʻomaopopo ʻaʻole ʻo Intel wale nō i kāna ʻimi e hana i ka hoʻomanaʻo uila ʻoi aku ka nui. Ua ʻōlelo pū ʻo Toshiba e pili ana i nā hoʻolālā e hana i ka PLC NAND i ka wā o ka Flash Memory Summit i mālama ʻia ma ʻAukake. Eia nō naʻe, ʻokoʻa loa ka ʻenehana o Intel: hoʻohana ka hui i nā cell memo floating-gate, ʻoiai ua kūkulu ʻia nā hoʻolālā o Toshiba a puni nā cell trap-based charge. Me ka hoʻonui ʻana i ka nui o ka mālama ʻana i ka ʻike, ʻo ka ʻīpuka lana ka hopena maikaʻi loa, ʻoiai e hōʻemi ana i ka mana like a me ke kahe ʻana o nā uku i loko o nā keena a hiki ke heluhelu i ka ʻikepili me ka liʻiliʻi o nā hewa. I nā huaʻōlelo ʻē aʻe, ʻoi aku ka maikaʻi o ka hoʻolālā ʻana o Intel no ka hoʻonui ʻana i ka density, i hōʻoia ʻia e nā hopena hoʻāʻo o ka QLC NAND i loaʻa i ke kālepa i hana ʻia me ka hoʻohana ʻana i nā ʻenehana like ʻole. Hōʻike ia mau hoʻāʻo ʻana i ka hōʻemi ʻana o ka ʻikepili i loko o nā keena hoʻomanaʻo QLC e pili ana i kahi ʻīpuka lana e hele mai ʻelua a ʻekolu mau manawa ʻoi aku ka lohi ma mua o nā pūnaewele QLC NAND me kahi pahele hoʻopiʻi.
E kūʻē i kēia kāʻei kua, ʻo ka ʻike a Micron i hoʻoholo ai e kaʻana like i kāna hoʻomohala hoʻomanaʻo flash me Intel, ma waena o nā mea ʻē aʻe, no ka makemake e hoʻololi i ka hoʻohana ʻana i nā cell trap charge, he mea hoihoi loa. Ke kūpaʻa nei ʻo Intel i ka ʻenehana kumu a hoʻokō ʻia i nā ʻōnaehana hou a pau.
Ma kahi o PLC NAND, e hoʻomohala mau ana, manaʻo ʻo Intel e hoʻonui i ka nui o ka mālama ʻana o ka ʻike i ka hoʻomanaʻo flash ma o ka hoʻohana ʻana i nā ʻenehana ʻē aʻe. Ma keʻano kūikawā, ua hōʻoia ka hui i ka hoʻololi kokoke i ka hana nui o 96-layer QLC 3D NAND: e hoʻohana ʻia ia i kahi kaʻa mea kūʻai aku hou. .
E hahai ʻia kēia e ka haku ʻana i ka hana ʻana o 144-layer QLC 3D NAND - e paʻi ia i nā drive hana i ka makahiki aʻe. He mea kupanaha ka hōʻole ʻana o Intel i ka manaʻo e hoʻohana i ka hoʻoheheʻe ʻekolu o nā kristal monolithic, no laila ʻoiai ʻo ka hoʻolālā 96-layer e pili ana i ka hui kūpaʻa o ʻelua mau kristal 48-layer, ʻike ʻia ka ʻenehana 144-layer ma 72-layer. "nā huahana semi-finished".
Me ka hoʻonui ʻana i ka nui o nā papa i nā kristal QLC 3D NAND, ʻaʻole i manaʻo nā mea hoʻomohala Intel e hoʻonui i ka hiki o nā kristal iā lākou iho. Ma muli o nā ʻenehana 96- a me 144-layer, e hana ʻia nā kristal terabit like me ka hanauna mua 64-layer QLC 3D NAND. ʻO kēia ma muli o ka makemake e hāʻawi i nā SSD e pili ana iā ia me kahi pae kūpono o ka hana. ʻO nā SSDs mua e hoʻohana i ka hoʻomanaʻo 144-layer ʻo Arbordale + server drives.
