262,144-Word x 16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE
This version : Jan. 2001
Preliminary
DESCRIPTION
The MSM514260E/ESL is a 262,144-word à 16-bit dynamic RAM fabricated in Okiâs silicon-gate CMOS
technology. The MSM514260E/ESL 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/ESL is available in a 40-pin plastic SOJ, 44/40-pin plastic TSOP. The
MSM514260ESL (the Self-refresh version) is specially designed for lower-power applications.
