MSM511664C/CL

DESCRIPTION

The MSM511664C/CL is a 65,536-word ¥ 16-bit dynamic RAM fabricated in Oki's silicon-gate CMOS

technology. The MSM511664C/CL achieves high integration, high-speed operation, and low-power

consumption because Oki manufactures the device in a quadruple-layer polysilicon/single-layer

metal CMOS process. The MSM511664C/CL is available in a 40-pin plastic SOJ or 44/40-pin plastic

TSOP.TheMSM511664CL(thelow-powerversion)isspeciallydesignedforlower-powerapplications.
