Manufacturer: Hitachi Semiconductor (now Renesas)

Overview: www.DataSheet4U.com HM514170D, HM514270D Series HM51S4170D, HM51S4270D Series 262,144-word × 16-bit Dynamic RAM ADE-203-672 (Z) Preliminary Rev. 0.0 Oct.

General Description

The Hitachi HM51(S)4170D, HM51(S)4270D Series are CMOS dynamic RAM organized as 262,144-word × 16-bit.

HM51(S)4170D, HM51(S)4270D Series have realized higher density, higher performance and various functions by employing 0.8 µm CMOS process technology and some new CMOS circuit design technologies.

The HM51(S)4170D, HM51(S)4270D Series offer fast page mode as a high speed access mode.
