SUMMARY DESCRIPTION
The M29F002B is a 2 Mbit (256Kb x8) non-volatile
memory that can be read, erased and reprogrammed. These operations can be performed using a single 5V 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. The
M29F002B is fully backward compatible with the
M29F002.
The memory is divided into blocks that can be
erased independently so it is possible to preserve
valid data while old data is erased. Each block can
be protected independently to prevent accidental
Program or Erase commands from modifying the
memory. Program and Erase commands are written to the Command Interface of the memory. An
on-chip Program/Erase Controller simplifies the
process of programming or erasing the memory by
taking care of all of the special operations that are
required to update the memory contents. The end
of a program or erase operation can be detected
and any error conditions identified. The command
set required to control the memory is consistent
with JEDEC standards.
The blocks in the memory are asymmetrically arranged, see Tables 3A and 3B, Block Addresses.
The first or last 64 Kbytes have been divided into
four additional blocks.
