Ib EPROM (tsis tshua muaj EROM), lossis tshem tau programmable nyeem nkaus xwb nco, yog hom programmable nyeem nkaus xwb nco (PROM) chip uas khaws nws cov ntaub ntawv thaum nws lub hwj huam mov raug kaw. Lub computer nco uas tuaj yeem khaws cov ntaub ntawv khaws cia tom qab lub hwj chim tau muab tua thiab rov qab los yog hu ua non-volatile.

Yog kuv nco ECC?
Rau SDRAM lossis DDR lub cim xeeb, tsuas yog suav tus lej ntawm cov chips dub me me ntawm ib sab ntawm koj lub cim xeeb uas twb muaj lawm. Yog tias tus naj npawb ntawm cov chips yog txawm tias koj tsis muaj ECC. Yog tus naj npawb ntawm cov chips khib ces koj muaj ECC. … Rau hom nonco nws yuav hais rau ntawm daim nplaum "ECC".
