The MR27V6466F is a 64 Mbit One Time Programmable Synchronous Read Only Memory whose configuration can be electrically switched between 4,194,304 x 16 bit (word mode) and 2,097,152 x 32 bit (double word mode) by the state of the WORD pin. The MR27V6466F supports high speed synchronous read operation using a single 3.3 V power supply.
