.Data Sheet.co.kr ¡ Semiconductor 4,194,304-Word x 16-Bit or 8,388,608-Word x 8-Bit 8-Word x 16-Bit or 16-Word x 8-Bit Page Mode One Time PROM DESCRIPTION 1A The MR27V6452D is a 64Mbit electrically Programmable Read-Only Memory with page mode. Its configuration can be electrically switched between 4,194,304 word x 16bit and 8,388,608 word x 8 bit. The MR27V6452D operates on a single +3.3V power supply and is TTL patible. The MR27 V6452D provides Page mode which can greatly reduce the read access time. Since the MR27V6452 D operates asynchronously , external clocks are not required , making this device easy-to-use. The MR27V6452D is suitable as large-capacity fixed memory for microputers and data terminals. It is manufactured using a CMOS double silicon gate technology and is offered in 44-pin SOP package.
