HM51W4405BS Series

1,048,576-word × 4-bit Dynamic Random Access Memory

ADE-203-686A (Z)

Rev. 1.0

Nov. 29, 1996

Description

The Hitachi HM51W4405BS Series is a CMOS dynamic RAM organized 1,048,576-word × 4-bit.

HM51W4405BS Series has realized higher density, higher performance and various functions by

employing 0.8 µm CMOS process technology and some new CMOS circuit design technologies. The

HM51W4405BS Series offers Extended Data Out (EDO) Page Mode as a high speed access mode. It has

the package variations of standard 26-pin plastic SOJ.
