Try looking at "Flash EPROM" devices. These are either bulk or
sector erasable (most require 12v Vpp but some from ATMEL are
5v only) and can be programmed byte-by-byte. The best have 
10,000 program-erase cycles and the cheapest cost about $160/Megabyte.
Much cheaper than full-featured EEPROM.

Some new handheld computers (for instance the new one from Scion in 
England) use Flash-EPROMS for simulated disk.

Manufacturers: Intel, Seeq, Atmel.
Future manufacturers: TI, Toshiba, NEC, SGS-Thomson Microelectronics.
