... Description The M29W800FT/B and M29W400FT/B are 8-Mbit (1 Mbit × 512 Kbit × 16) and 4-Mbit (512 Kbit × 256 Kbit × 16) non-volatile memory devices that can be read, erased and reprogrammed. These operations can be performed using a single low voltage (2 3.6 V) supply. On power-up the memory defaults to its read mode where it can be read in the same way as a ROM or EPROM ...
