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.
