It's an EEPROM, not an EPROM. EEPROM is just a type of EPROM - the type where the erasing is done Electrically (as opposed to erasing by UV light, for instance) "EPROM" is the more general term; without further qualification, it just means any type of Eraseable Programmable Read-Only Memory Two specific types of EPROM are: UVEPROM - where the erase is done by UV light; Can you produce even one datasheet for a "UVEPROM" that actually calls it a UVEPROM? Saying they're essentially the same is like saying a MOSFET and a vacuum tube are essentially the same. They're not, and that's all there is to it. The EPROM is essentially random access for both reads and writes, though the conditions are quite different. That's not the case with an EEPROM. EEPROM - where the erase is done Electrically
Note that "Flash" is a specific type of electrical erasure technology Note also that "EEPROM" is sometimes used idiomatically to indicate a device specifically designed for data storage - as opposed to code storage... That's like saying an automobile is a type of wheelbarrow. Ask someone who knows about the internals. RE |
