- I think it is not practically possible. You must refresh those
- DRAM at ms interval, so if you had a SOLID DRIVE based on DRAM,
- you have to use an BIG bettery to back it up, as big as an
- auto battery ? I don't know. But I guess this is why those RE guys
- using SRAM in their version of SD.
- Even though you run up window from a SD, chances are your VGA card
- may not fast enough to refresh the monitor screen.
