Kumbukirani kuti RAM Memory (Random Access Memory) yomwe imagwiritsidwa ntchito pa makompyuta ndi yovuta. Izi zikutanthauza kuti mutatsegula kompyuta, zonse zomwe zasungidwa mu chipsesiti cha kukumbukira zimatayika. Mosiyana ndi izi, kukumbukira kukumbukira sikungokhala kosasinthasintha zomwe zimatanthawuza kuti chidziwitso chomwe chimagwiritsidwa ntchito pamtundu uwu wamakono chikumbukika pamene mphamvu idula. Mauthenga olembedwera ndi kuchotsedwa kuzipangizo zapaderazi zapadera zimagwiritsidwa ntchito pakompyuta m'malo mwa njira zamagetsi - zofanana ndi EEPROM yakale komanso yocheperako. Fomu iyi ya teknoloji yolimba ikusiyana ndi yosungirako makina monga zovuta zowonongeka ; Zomwe zili mu nkhaniyi zimasungidwa pogwiritsa ntchito magnetism. Mtundu wochuluka wa magetsi omwe amagwiritsidwa ntchito masiku ano ndi NAND - dzinali latengedwa kuchokera ku chipatala chapamwamba cha NAND chotengera cha NAND chifukwa chikumbutso cha flash chikugwiritsa ntchito chipinda choyandama cha MOSFET chimene chimapangidwira mofananamo.
Kodi Zimagwira Ntchito Bwanji?
Monga momwe tafotokozera kale, kukumbukira kwagudumu kumagwiritsa ntchito zowonongeka zitseko. Izi zimakonzedwa mu gridi. M'malo mozengereza kokha omwe ali ndi chipata chimodzi, flash NAND kukumbukira ili ndi zipata ziwiri. Kukhala ndi zipata ziwiri zimathekera kuti 'kusungira' mpweya pakati pa zipata ziwiri kuti zisachoke - izi ndizofunika kwambiri ndipo zimapangitsa kuti aliyense asungidwe bwino. Ndipotu, mpweya woterewu (womwe umaimira chidziwitso) pa chip ukhoza kukhalabe wotsekedwa kwa zaka zambiri - kapena mpaka mutachotsa malingaliro. Zosungidwa zomwe zasungidwa zimachotsedwa pochotsa magetsi kuchoka pakati pa zipata ziwiri pogwiritsa ntchito chipata chapadera choyandama chomwe chimakhala chosawunikira makina osungira malingaliro.
Zida Zamakono Zogwiritsa Ntchito Mafilimu
Pali zipangizo zamagetsi zamagetsi zomwe zimagwiritsa ntchito NAND flash memory monga yosungirako. Njira zina zosungirako zosungirako zimagwiritsanso ntchito NAND kukumbukira kukumbukira. Mitundu ya hardware yomwe mungathe kuigwiritsa ntchito yomwe ikugwiritsira ntchito makina awa ndi awa:
- Masewera a MP3
- Othandiza Osewera a Media ( PMP s)
- Makhadi aang'ono / zojambula monga MicroSD ndi MicroSDHC
- Ma drive a USB
- Mafoni / Mafoni
- Zida zina zamagetsi
Ubwino ndi Kuipa
Monga teknoloji yonse, pali ubwino ndi kuwononga kugwiritsa ntchito izo. Chinthu chimodzi chodziwika bwino chogwiritsa ntchito kukumbukira (ndi zipangizo zomwe zimagwiritsa ntchito) ndikuti palibe zipangizo zomwe zingathe kuwonongeka kapena kuwonongeka mosavuta. Kwa osewera ma MP3 ndi zipangizo zina zomwe zingasewere nyimbo za digito, izi ndizosungirako zosungira zomwe sizikugwedezeka, kugwedezeka kwa maginito, etc. Kukumbukirika ndikutsika mtengo ndipo kungakhale kusankha kosungirako - kwa onse opanga zipangizo zamakina ndi ogula omwe akufuna kugula zosungirako zowonjezera mofanana ndi maka maka makadi.
Komabe, kukumbukira kukumbukira kuli ndi zolakwika zake. Poyambira, ili ndi moyo wautali pa nthawi yomwe deta ingalembedwe kumalo omwewo a kukumbukira. Izi zimadziwika kuti P / E mapulogalamu (pulogalamu-kuchepetsa zozungulira) ndipo kawirikawiri amakhala ndi pafupifupi 100,000 omwe amawerenga / amalemba. Pambuyo pake, kusungirako kwawuniko kudzatsikira modalirika pamene chikumbumtima cha NAND chimachepa. Kuvala kukumbukira kungathe kuwonetsedwa pamaseĊµera a MP3 ndi zipangizo zina zogwiritsira ntchito firmware zomwe zimafalitsa zolemba izi zowerengera / kulembetsa mosavuta kuti chipangizocho chikhale zaka zambiri ndikugwiritsidwa ntchito. Chinthu chinanso chosavuta kukumbukira kukumbukirabe sichingafanane ndi mphamvu za TB (Terabyte) zomwe timaziwona muzitsulo zovuta kwambiri ndipo motero sayansiyi sitingagwiritsidwe ntchito (komabe) yosungirako misala ambiri.
