Ndibonisa ngokucacileyo eyona ndlela ilula yokubuyisela idatha kwimemori ye-NAND ye-smartphone, nokuba kutheni uyifuna. Kwezinye iimeko, ifowuni ayisebenzi ngenxa yomonakalo weprosesa, ibhodi ekhukulayo engenakulungiswa, kwezinye iimeko, ifowuni ivaliwe, kwaye idatha kufuneka igcinwe.
Ndinethamsanqa ngokwaneleyo ukuba ndisebenze kwi-fix-oscomp, icandelo lenkampani ye-OSKOMP ukulungiswa kwezixhobo zedijithali. Apha ndiye ndaqhelana nale ndlela ekusebenzeni.
I-NAND lolona hlobo lwenkumbulo yeflash edla ngokusetyenziswa kwii-smartphones zanamhlanje.
Uyilo lwe-NAND ngokweWikipedia
Uyilo lwe-NAND luluhlu olunamacala amathathu. I-matrix iyafana ne-NOR, kodwa endaweni ye-transistor enye kwindawo nganye yokuhlangana, ikholamu yeeseli eziqhagamshelwe kuthotho ifakiwe. Olu luyilo luvelisa amatyathanga amaninzi esango kwindawo enye. Ukuxinana kwesakhiwo kunokunyuswa ngokumangalisayo (emva kwayo yonke into, i-conductor yesango enye kuphela ihambelana neseli enye kwikholamu), kodwa i-algorithm yokufikelela kwiiseli zokufunda nokubhala iba nzima ngakumbi. Kukwakho neeMOSFET ezimbini ezifakwe kumgca ngamnye. I-Bit line khetha i-transistor ebekwe phakathi koluhlu lweeseli kunye ne-bit line. Kwaye i-transistor yomhlaba wolawulo ephambi komhlaba (umhlaba ukhethe i-transistor).
Isigulana sanamhlanje se-Xiaomi Mi Max 3:
Emva kwezandyondyo zemvula yayeka ukulayita.
Ukuxilongwa kubonise ukuba iprosesa ifile ngakumbi kunokuphila. Umxhasi udinga idatha kwifowuni kwaye kunokwenzeka ukubuyisela isixhobo ngokwalo.
Ibhodi yacocwa, kodwa asinakuthatha indawo yeprosesa, kuba iprosesa kunye nememori ye-NAND zidityaniswe kusetyenziswa isitshixo kwaye siyazitshintsha ngababini. Kule meko, sithatha ibhodi yabanikezeli kwimodeli engabizi kakhulu; kule meko, i-Xiaomi Redmi Note 5 iya kwenza.
Sifudumeza ibhodi ngokusebenzisa ukufudumeza okuphantsi.
Sifaka i-flux.
Yifudumeze ngesixhobo sokomisa iinwele.
Sisusa imemori ye-NAND.
Coca nayiphi na i-flux eseleyo.
Sijonga abafowunelwa.
Sifaka imemori kwisixhobo sokufunda.
Kwimeko yethu, sifuna icandelo ledatha yomsebenzisi kunye neefayile zokuqalisa.
Isantya ukuya kuthi ga kwi-10 MiB/s. Kodwa kuya kufuneka ulinde ixesha elide. Inkqubo yokufunda ithatha umndilili weeyure ezi-2.
Ngale ndlela unokwandisa inani lememori kunye ne-RAM ukuba kuyimfuneko.
Sirekhoda idatha evela kumnikeli kwimemori.
Sithengisa imemori kunye neprosesa kumnikeli, yivule kwaye ujabule!
