ok it stands for electroniclly programmable read only memory, i think, so why does the pc world have these oxymorons given its not read only, you can also program it.edit good to see the site is up again cheers and thanks to the site owner for continuing to provide a service and all his helpers well done AUSTECH FIGHTS BACK WITH PERSISTENCE

yes but once its a zero you can't make it a one.

Unless its UV erasable type.

Unless its UV erasable type.

But not if I want to erase just a little...bit...

phew z80 what r u on about, try eeprom, i use hex so dont worry about binary it looks after itself

sure...but the thread title is eprom not eeprom.

Sort of right
EPROM stands for Erasable programmable read only memory
EEPROM stands for Electronically Erasable programmable read only memory


EPROM has to be exposed to VU light to be erased (they usually have a paper sticker over the section that has to be exposed)

EEPROM has to (usually) be removed from the device and have Voltage's to certain pins to be erased.

Sort of right...I think it has to be UV light........

I'm just being picky. My blood sugar get's low about now.

EPROM actually stands for ERASABLE PROGRAMMABLE READ ONLY MEMORY (not Electronically)

EPROM's are an array of floating-gate transistors individually programmed by an electronic device that supplies higher voltages than those normally used in electronic circuits. Once programmed, an EPROM can be erased only by exposing it to strong ultraviolet light.

Whereas on the other hand a PROM comes with all bits reading as 1. Burning a fuse during programming causes its bit to read as 0. The memory can be programmed just once after manufacturing by "blowing" the fuses (using a PROM blower), which is an irreversible process.

Confusing subject hey !

It's Roms that confuse people most , because technically they are programmable or they couldn't be "Read Only Memory" Only problem is that you only get one chance because once they are written to thats it , if you get it wrong first time to bad.

All Roms are technically ROMOTP or MASK ROMS ,"Read only memory one time programmable"


It just for ease or maybe lack of knowledge that people call all types of memory EPROMS , we know what they mean and in many cases you can use a ROM , Eprom , EEprom or even Ram for the same application .

Then theres IBM's "Efuse", which is being used to stop you downgrading your xbox 360 firmware, among other things.
