MSM51V18160F
1,048,576-Word x 16-Bit DYNAMIC RAM : FAST PAGE MODE TYPE
This version:Oct.1999
DESCRIPTION
The MSM51V18160F is a 1,048,576-word
´
16-bit dynamic RAM fabricated in Oki’s silicon-gate CMOS
technology. The MSM51V18160F 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
MSM51V18160F is available in a 42-pin plastic SOJ or 50/44-pin plastic TSOP.
