Non-volatile memory feem ntau yog hais txog kev khaws cia hauv semiconductor nco chips, uas khaws cov ntaub ntawv hauv cov chaw nco hauv ntab uas muaj cov ntab- rooj vag MOSFETs (hlau-oxide-semiconductor teb -effect transistors), suav nrog flash nco cia xws li NAND flash thiab solid-state drives (SSD).
Dab tsi yog ib txwm khaws cia rau hauv lub cim xeeb uas tsis yog-volatile?
ROM lossis Read Only Memory yog hom kev nco tsis hloov pauv uas txhais tau tias nws khaws nws cov ntaub ntawv txawm tias lub hwj chim raug kaw. Txawm li cas los xij feem ntau cov ntaub ntawv hauv ROM tsis tuaj yeem hloov pauv. Cov khoos phis tawj siv ROM nco thaum pib thiab muaj cov lus qhia txaus kom tau lub computer mus.
Yuav ua li cas khaws cia siv ib hom kev nco tsis hloov pauv?
Solid-state storage feem ntau yog siv qhov sib txawv ntawm cov cim xeeb tsis hloov pauv hu ua NAND flash. SSDs tsis muaj qhov txav txav, thiab lawv muaj peev xwm ua tau zoo dua li cov cuab yeej hais txog HDDs thiab daim kab xev, uas siv lub taub hau los nyeem thiab sau cov ntaub ntawv rau cov khoom sib nqus.
Puas yog SSD cia tsis hloov lossis tsis hloov pauv?
Ib qho SSD, lossis lub xeev lub zog tsav, yog hom khoom siv khaws cia siv hauv khoos phis tawj. Qhov no non-volatile storage xov xwm khaws cov ntaub ntawv tsis tu ncua ntawm cov khoom siv flash nco. SSDs hloov ib txwm hard disk drives (HDDs) hauv computers thiab ua tib yam haujlwm yooj yim li lub hard drive.
Lub cim xeeb twg yog lub npe hu ua kev nco tsis muaj zog?
4 ROM. Tsis-volatile nco yog lub cim xeeb uas khaws nws cov txiaj ntsig txawm tias lub zog raug tshem tawm. Cov ntaub ntawv yav dhau los ntawm kev nco tsis hloov pauv suav nrog ntau hom ntawv nyeem nkaus xwb (ROM).
