[sdiy] SRAM question

[Byron G. Jacquot]

>Ok, so I fund a Flash Ram chip and looked at the pin out and it looks like it works the same way as the SRAM as far as data I/O and Addressing. So the thing doesn't need any backup power supply?

Flash RAM?

Do you maybe mean Flash ROM?  Flash ROM is not random-access.  It uses a paging scheme - you have to erase a sector at a time, then burn data into it, both using a command sequence.  Both operations are much slower than a true RAM...but they are indeed nonvolatile, without backup power of any sort.
