So, these are the characteristics of the ROM: Input products are hard-wired and include all possible minterms. While the “electrically erasable” part of EEPROMs name might seem like a throwaway phrase, don’t confuse this type of memory with“EPROM,” which stands for Erasable Programmable Read-Only Memory. ROMs are integrated circuits that contain data and most often cannot be altered. The flash memories find application in ______ There are some types that can be somewhat modified that include programmable ROM (PROM), erasable programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM) and Flash, which is a type of EEPROM. EEPROM is Electrical EPROM, that uses Electrical signals to erase the Program stored. The key difference between RAM and ROM is that RAM is basically a read-write memory whereas, ROM is a read only memory. Also Read: Difference Between Memory And Registers. Sanfoundry Global Education & Learning Series – Computer Organisation and Architecture.
