SUMMARY DESCRIPTION
The M29F800A is an 8 Mbit (1Mb x8 or 512Kb
x16) non-volatile memory that can be read, erased
and reprogrammed. These operations can be per-
formed 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 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 writ-
ten 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.
