storage chipA semiconductor circuit that holds data until purposely erased. Flash memory is the predominant technology for solid state storage because it can be erased although not as quickly as a hard disk.
ROM and programmable ROM (PROM) chips hold their data permanently and cannot be changed. Erasable PROMs (EPROMS) can be erased manually after they are removed, while electrically erasable PROMs (EEPROMs) can be erased in place. EEPROMs were the precursor to flash memory. See storage vs. memory, flash memory, ROM, PROM, EPROM, EEPROM and solid state drive.
