Nws yog ib qho array ntawm floating-gate transistors ib tus zuj zus programmed los ntawm cov khoom siv hluav taws xob uas muab cov hluav taws xob ntau dua li cov uas ib txwm siv hauv digital circuits. Thaum programmed, EPROM tuaj yeem raug tshem tawm los ntawm kev nthuav tawm nws mus rau muaj zog ultraviolet lub teeb ci (xws li los ntawm lub teeb mercury-vapor)
Koj tuaj yeem tshem tawm cov ntaub ntawv los ntawm EPROM li cas?
Tsis zoo li PROM (Programmable Read only Memory) Nws muaj peev xwm tshem tawm cov ntaub ntawv los ntawm EPROM tsis hloov pauv los ntawm nthuav tawm nws mus rau lub zog hluav taws xob ultraviolet lub teeb los ntawm lub cuab yeej hu ua EPROM eraser. Programmers siv EPROM programmer los sau cov ntaub ntawv ntawm EPROM.
Lub teeb twg siv los lwv cov ntaub ntawv hauv EPROM?
EPROM yog hom ROM nti uas tuaj yeem khaws cov ntaub ntawv txawm tias tsis muaj hluav taws xob. Cov ntaub ntawv tuaj yeem raug tshem tawm thiab rov kho dua los ntawm kev siv ultraviolet (UV) lub teeb. Lub teeb UV tshem tawm cov ntaub ntawv ntawm lub nti kom nws tuaj yeem rov ua haujlwm dua.
Qhov twg ntawm cov txheej txheem hauv qab no yog siv los lwv cov ntsiab lus ntawm EEPROM?
EEPROM tuaj yeem tsim kho thiab tshem tawm hluav taws xob siv field electron emission(feem ntau paub hauv kev lag luam li "Fowler-Nordheim tunneling").
Dab tsi tshwj xeeb siv los sau rau thiab tshem tawm EEPROM?
Sau rau thiab tshem tawm EPROM, koj xav tau lub cuab yeej tshwj xeeb hu ua a PROM programmer lossis PROM burner.
