262,144-Word x 16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE
This version:Aug.2000
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.
