well from what l remember they are all different even if the do the same thing eprom can be erased by uv light but with no window it doesnt erase cause theres no light eeprom can be erased by electricity...hence the extra e in the name.. flash is also erasable by electricity but it has ram sitting on top of the eeprom which can speed the process up as you write to the ram and it does the transfer in the background...reading reads from the ram also as it always has the same data as the eeprom under it... it is all a bit more complicated than this of course to the chip designers and there are different memory making methologies used but to the end user the above three are about all you have to know... whether they use what the quote is another story and would be hard to argue without the use of a very strong microscope...a electron would do the job.. ----- Original Message ----- From: "Bob Ammerman" To: Sent: Sunday, September 24, 2000 5:40 AM Subject: Re: [PIC] > I'm not 100% sure but I do believe that FLASH != EPROM. > > Bob Ammerman > RAm Systems > (contract development of high performance, high function, low-level > software) > > ----- Original Message ----- > From: Nigel Goodwin > To: > Sent: Saturday, September 23, 2000 1:40 PM > Subject: Re: [PIC] > > > > In message <017f01c02503$b1bf2e80$1bc91440@sciencekit.com>, Bob Ammerman > > writes > > >Close, but I'm pretty sure the 16C84 was eeprom, not flash based. > > > > Yes, the 16C84 was EEPROM based, but isn't the 16F84 EEPROM based as > > well?.
