GENERAL DESCRIPTION
The MR27V3252J is a 32 Mbit electrically One Time
Programmable Read-Only Memory with page mode. Its
configuration can be electrically switched between
2,097,152-word × 16-bit and 4,194,304-word × 8-bit by the
state of the BYTE# pin. The MR27V3252J supports high
speed asynchronous read operation using a single 3.3V power
supply.
