Steve,
Do you recall our previous discussion regarding adding both logic and flash memory to a single chip? You replied...
The main issue is the processing, as the flash process and logic process are optimized for different things. When you integrate flash into your process, you tend to make non-optimal flash and, perhaps more importantly, you typically don't have flash experts on your team to help out (because they are all still working for flash groups).
I had a follow-up question somewhat related to this.
I have found a very disturbing feature of my portable P/PC, the Cassiopeia E-100 (and my H/PC version, the NEC MobilePro 770). The Windows CE operating system is located on a ROM memory chip, while any additional software or any files I create (phone lists, to do lists, dictionaries...) are stored in the 32 MB of RAM memory. The programs also require a chunk of RAM for operation, so the entire RAM module cannot be devoted to storage alone.
This RAM memory must be DRAM, because you need a small lithium battery (like a watch battery) to retain the data. I learned this when I returned from a 3 week vacation this summer only to find all my information had been erased. Fortunately I had backed some of the information up on CompactFlash cards and on my PC.
My question is...
Why not make the RAM non-volatile? It would eliminate the need for a back-up power source altogether.
It seems like a no-brainer.
