The thing in common between EEPROMS and FLASH ROM is that they can be reprogrammed many times. Literally, "EEPROM" just means Electrically-Eraseable PROM - and, therefore, "Flash" is just a type of EEPROM. There seems to be an increasing number of people using "EEPROM" in this sense. More traditionally, "EEPROM" has been taken to indicate specifically devices that are intended for Data storage (as opposed to "Flash", which the same idiom would assume is for code storage). with a flash, you had to write a special sequence of code, and you can only write chunks of data into FLASH ROM where as in an EEPROM, you can write only one byte of data at any address if you wanted to Yes, that's the "traditional" idiom - which assumes more than the initials themselves tell you! Just like "RAM" is almost invariably taken to imply "volatile" - even thought the initials themselves say nothing about that at all! |
