I have used a relative of this device (by the sound of it) called a
DiskOnChip (I wish people wouldn't mIx cases, it's a pain to type). This
uses a flash memory in a 32 pin "eeprom" format chip to emulate a disk
drive under DOS. You can get them in capacites up to 72 MB
but... they're expensive. I think the 72MB version is about 900 pounds.
It has a device driver that implements their own proprietary filesystem
called TrueFFS which sounds like it does all the Reed-Solomon stuff
on the PC.
Oh yes, it also does other smarts, like background deletions (slow)
and levelling the write operations across all the pages to prolong the
device life. I think Toshiba invented the technology and Samsung
second-source the devices.

electronically :-)
