Mokhoa oa ho sebetsa oa Nand Flash
NAND Flash e sebetsoa ho tsoa ho thepa ea pele ea silicon, 'me thepa ea silicon e sebetsoa hore e be li-wafers, tseo ka kakaretso li arotsoeng ka lisenthimithara tse 6, lisenthimithara tse 8 le lisenthimithara tse 12.Sephaphatha se le seng se hlahisoa ho ipapisitsoe le sephaphatha sena kaofela.Ee, ke bokae ba sephaphatha se le seng se ka khaotsoang ho tloha sephaphatha ho khethoa ho ea ka boholo ba lefi, boholo ba sephaphatha le sekhahla sa tlhahiso.Hangata, makholo a lichifi tsa NAND FLASH li ka etsoa ka sephaphatha se le seng.
Sephaphatha se le seng pele se paka se fetoha Die, e leng sengoathoana se sehiloeng ho Wafer ka laser.E 'ngoe le e' ngoe ea Die ke chip e ikemetseng e sebetsang, e entsoeng ka li-circuits tse ngata tsa transistor, empa e ka kenngoa e le yuniti qetellong E fetoha flash particle chip.E sebelisoa haholo masimong a lisebelisoa tsa elektroniki tsa bareki joalo ka SSD, USB flash drive, karete ea memori, jj.
Sephaphatha se nang le sephaephe sa NAND Flash, sephaphatha se lekoa pele, 'me ka mor'a hore tlhahlobo e fete, sea khaoloa ebe se hlahlojoa bocha ka mor'a ho seha,' me lefu le tsitsitseng, le tsitsitseng le le nang le matla a feletseng lea ntšoa, ebe lea pakoa.Teko e tla etsoa hape ho kenyelletsa likaroloana tsa Nand Flash tse bonoang letsatsi le letsatsi.
Tse ling tse holim'a sephaphatha mohlomong ha lia tsitsa, li senyehile ka mokhoa o itseng 'me kahoo ha li na matla a lekaneng, kapa li senyehile ka ho feletseng.Ha ho nahanoa ka tiisetso ea boleng, feme ea pele e tla phatlalatsa hore lefu lena le shoele, le hlalosoang ka ho hlaka e le ho lahla lihlahisoa tsohle tsa litšila.
Feme ea mantlha ea liphutheloana tsa Flash Die e tla kenya ho eMMC, TSOP, BGA, LGA le lihlahisoa tse ling ho latela litlhoko, empa ho boetse ho na le bofokoli ba ho paka, kapa ts'ebetso e se maemong a holimo, likaroloana tsena tsa Flash li tla tlhotloa hape, 'me lihlahisoa li tla tiisetsoa ka liteko tse thata.boleng.

Tlas'a maemo a hajoale moo NAND Flash ea kantle ho naha e busang 'maraka, moetsi oa China oa NAND Flash (YMTC) o hlahile ka tšohanyetso ho ba le sebaka 'marakeng.3D NAND ea eona ea 128-layer 3D NAND e tla romela lisampole tsa 3D NAND tsa 128-layer ho molaoli oa polokelo karolong ea pele ea 2020. Baetsi, ba ikemiselitseng ho kenya tlhahiso ea lifilimi le tlhahiso ea bongata karolong ea boraro, ba reriloe ho sebelisoa lihlahisoa tse sa tšoaneng tsa ho qetela tse joalo. joalo ka UFS le SSD, 'me e tla romelloa lifemeng tsa module ka nako e ts'oanang, ho kenyeletsoa lihlahisoa tsa TLC le QLC, ho atolosa setsi sa bareki.
Mokhoa oa ts'ebeliso le nts'etsopele ea NAND Flash
Joalo ka mokhoa o batlang o sebetsa oa ho boloka li-hard drive, NAND Flash e na le litšobotsi tsa eona tsa 'mele.Nako ea bophelo ea NAND Flash ha e lekane le nako ea bophelo ea SSD.Li-SSD li ka sebelisa mekhoa e fapaneng ea tekheniki ho ntlafatsa nako ea bophelo ea li-SSD ka kakaretso.Ka mekhoa e fapaneng ea tekheniki, nako ea bophelo ea li-SSD e ka eketsoa ka 20% ho isa ho 2000% ha e bapisoa le ea NAND Flash.
Ka lehlakoreng le leng, bophelo ba SSD ha bo lekane le bophelo ba NAND Flash.Bophelo ba NAND Flash bo khetholloa haholo ke potoloho ea P/E.SSD e entsoe ka likaroloana tse ngata tsa Flash.Ka algorithm ea disk, bophelo ba likaroloana bo ka sebelisoa ka katleho.
Ho ipapisitsoe le molao-motheo le ts'ebetso ea tlhahiso ea NAND Flash, bahlahisi bohle ba ka sehloohong ba memori ea flash ba sebetsa ka mafolofolo ho nts'etsapele mekhoa e fapaneng ea ho fokotsa litšenyehelo ka hanyane ka hanyane ea memori ea flash, 'me ba ntse ba etsa lipatlisiso ka mafolofolo ho eketsa palo ea likarolo tse otlolohileng ho 3D NAND Flash.
