General Description
The A29DL324 is a flash memory organized of 33,554,432
bits and 71 sectors. Sectors of this memory can be erased
at a low voltage (2.7 to 3.6 V) supplied from a single power
source, or the contents of the entire chip can be erased.
Two modes of memory organization, BYTE mode
(4,194,304 words × 8 bits) and WORD mode (2,097,152
words × 16 bits), are selectable so that the memory can be
programmed in byte or word units.
The A29DL324 can be read while its contents are being
erased or programmed. The memory cell is divided into two
banks. While sectors in one bank are being erased or
programmed, data can be read from the other bank thanks
to the simultaneous execution architecture. The banks are
8 Mbits and 24 Mbits.
This flash memory comes in two types. The T type has a
boot sector located at the highest address (sector) and the
B type has a boot sector at the lowest address (sector).
Because the A29DL324 enables the boot sector to be
erased, it is ideal for storing a boot program. In addition,
program code that controls the flash memory can be also
stored, and the program code can be programmed or
erased without the need to load it into RAM. Eight small
sectors for storing parameters are provided, each of which
can be erased in 8 Kbytes units.
Once a program or erase command sequence has been
executed, an automatic program or automatic erase
function internally executes program or erase and
verification automatically.
Because the A29DL324 can be electrically erased or
programmed by writing an instruction, data can be
reprogrammed on-board after the flash memory has been
installed in a system, making it suitable for a wide range of
applications.
