DESCRIPTION
The M29F400 is a non-volatile memory that may
be erasedelectrically at theblock or chip leveland
programmed in-systemonaByte-by-Byte orWord-
by-Word basis using only a single 5V V

supply.
For Program and Erase operations the necessary
high voltages are generated internally. The device
can also be programmed in standard program-
mers.
The arraymatrix organisation allowseach blockto
be erased and reprogrammed without affecting
other blocks. Blocks canbe protectedagainst pro-
