Ngikhombisa ngokubukeka indlela elula yokuthola idatha kumemori ye-NAND ye-smartphone, kungakhathalekile ukuthi kungani uyidinga. Kwezinye izimo, ifoni ayisebenzi ngenxa yokulimala kweprosesa, ibhodi lesekhethi eligcwele amanzi elingenakulungiseka, kwezinye izimo, ifoni ivaliwe, futhi idatha kufanele igcinwe.
Ngaba nenhlanhla yokusebenzela i-fix-oscomp, ingxenye yokulungisa idijithali ye-OSKOMP. Lapha ngajwayelana nokusebenza ngale ndlela.
I-NAND iwuhlobo lwenkumbulo ye-flash evame ukusetshenziswa kuma-smartphones anamuhla.
I-NAND design ngokusho kwe-Wikipedia
Idizayini ye-NAND iyi-array enezinhlangothi ezintathu. Isisekelo siyi-matrix efanayo nanjenge-NOR, kodwa esikhundleni se-transistor eyodwa empambanweni ngayinye, kufakwa ikholomu yamaseli axhumeke ngochungechunge. Kulo mklamo, amaketanga amaningi esango atholakala empambana-mgwaqo owodwa. Ubuningi bokupakisha bungakhuphuka kakhulu (phela, umqhubi wesango elilodwa kuphela olingana neseli eyodwa kukholamu), kodwa i-algorithm yokufinyelela amaseli okufunda nokubhala iba inkimbinkimbi ngokuphawulekayo. Kukhona futhi ama-MOSFET amabili kulayini ngamunye. I-transistor yokulawula ye-bit line (i-English bit line khetha i-transistor), ephakathi kwekholomu yamaseli nomugqa omncane. Futhi i-transistor yokulawula umhlabathi, ephambi komhlabathi (i-English ground khetha i-transistor).
Isiguli sanamuhla se-Xiaomi Mi Max 3:
Ngemva kokugcwalisa iyeka ukuvuleka.
Ukuxilongwa kubonise ukuthi iphrosesa kungenzeka ifile kunokuthi iphile. Iklayenti lidinga idatha kusuka efonini futhi kungenzeka ukubuyisela idivayisi ngokwayo.
Ibhodi lihlanziwe, kodwa asikwazi ukumiselela iphrosesa, njengoba iphrosesa nememori ye-NAND kubhanqwe ngokhiye futhi siyazishintsha ngamabhangqa. Kulokhu, sithatha imali yomnikeli kumodeli eshibhile, kulokhu i-Xiaomi Redmi Note 5 izokwenza.
Sifudumeza ibhodi ngokushisa okuphansi.
Sifaka i-flux.
Zifudumeze ngomshini wokomisa izinwele.
Sisusa inkumbulo ye-NAND.
Hlanza i-flux esele.
Sibheka abathintwayo.
Faka inkumbulo kumfundi.
Esimweni sethu, sidinga isigaba sedatha yomsebenzisi namafayela okuqalisa.
Ukusheshisa kufika ku-10 MiB/s. Kodwa kuzothatha isikhathi eside ukulinda. Inqubo yokufunda ithatha isilinganiso samahora angu-2.
Ngakho-ke, ungakwazi ukwandisa inani lememori ne-RAM uma kunesidingo.
Sibhala idatha kumemori evela kumnikeli.
Sithengisa inkumbulo nephrosesa kumnikeli, yivule futhi ujabule!
Спасибо за внимание!
