Flash EPROMS

For years nothing much happened in the field of nonvolatile read/write memory components until the EEPROM (Electrically Erasable and Programmable Read Only Memory), followed within a short time by the Flash EPROM, came along. The EEPROM has (not yet) lived up to its early promise, but the Flash EPROM has made a more auspicious start. Already, within two years of its commercial introduction, these devices are readily available and have been used in some commercial equipment. Chip manufacturers say (and, no doubt, hope) that the Flash EPROM has a promising future.
