DESCRIPTION
The MSM514260E/ESL is a 262,144-word × 16-bit dynamic RAM fabricated in Oki’s 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.
