non-volatile memory
EPROM - Erasable Programmable Read Only Memory.
I believe you are refering to an e-prom.n Or specifically an UVeProm It is a ram chip that retains it's memory. Check this: http://secure.transtronics.com/I-PP3USB.htm
Its called an EPROM (erasable programmable read-only memory). There is a small window on the chip which erases the contents when a strong ultraviolet light is shone through it.

Here ya go found this on the Internet for you: Acronym for erasable programmable read-only memory, and pronounced ee-prom, EPROM is a special type of memory that retains its contents until it is exposed to ultraviolet light. The ultraviolet light clears its contents, making it possible to reprogram the memory. To write to and erase an EPROM, you need a special device called a PROMprogrammer or PROM burner. An EPROM differs from a PROM in that a PROM can be written to only once and cannot be erased. EPROMs are used widely in personal computers because they enable the manufacturer to change the contents of the PROM before the computer is actually shipped. This means that bugs can be removed and new versions installed shortly before delivery.
Yes, ROM (Read Only Memory) retains its contents even when the computer is turned off. RAM (Random Access Memory), on the other hand, loses its content the instant power is switched off.
Nickel-Cadmium
forget password flash memory
A type of ROM(Read Only Memory) which can be programmed and can be erased after programming using ultraviolet rays.
RAM
It's called "Volatile Memory".
M- subtracts the value showing from the contents of the memory. M+ adds value showing to the contents of the memory You should be able to clear the memory with MC or some similar button.
Non-volatile. It retains its memory even if power is removed.
