 		 #125460 - FLASH RAM
Responding to: ???'s previous message
DON'T try using FLASH as RAM without a lot of care. FLASH has a very finite number of erase cycles before it becomes unreliable - as few as 50,000 cycles. That's only 12,000 hours of data, or 500 days.

If you got cunning, and used say 32K in rolling blocks, so you only erase a block 1/16th of the time, you would get 22 years out of it however.
