MSM5116400D

4,194,304-Word ´ 4-Bit DYNAMIC RAM : FAST PAGE MODE TYPE

DESCRIPTION

The MSM5116400D is a 4,194,304-word ´ 4-bit dynamic RAM fabricated in Oki’s silicon-gate CMOS technology. The MSM5116400D 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 MSM5116400D is available in a 26/24-pin plastic SOJ, 26/24-pin plastic TSOP.

Notes: *1. The input voltage is VCC + 2.0V when the pulse width is less than 20ns (the pulse width is with respect to the point at which VCC is applied).

*2. The input voltage is VSS - 2.0V when the pulse width is less than 20ns (the pulse width respect to the point at which VSS is applied).
