Serial RAM, EEPROM, FLASH or RAMTRON.

RAMTROM is a manufacturer; the technology is called FRAM - which is a kind of non-volatile SRAM, without the need for batteries, erase cycles, etc.

FRAM is also available from Fujitsu - possibly others?

RAMTRON have an 8051 with on-chip FRAM.

Freescale have recently anounced commercial availability of their MRAM non-volatile RAM:
