MSM514260E

262,144-Word x 16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE

DESCRIPTION

The MSM514260E is a 262,144-word

× 16-bit dynamic RAM fabricated in Oki’s silicon-gate CMOS technology.

The MSM514260E achieves high integration, high-speed operation, and low-power consumption because Oki

manufactures the device in a quadruple-layer polysilicon/double-layer metal CMOS process. The MSM514260E

is available in a 40-pin plastic SOJ, 44/40-pin plastic TSOP.
