HM514280AL Datasheet 18-bit Dynamic Random ACcess Memory

Manufacturer: Renesas

Overview: HM514280A/AL Series 262,144-word × 18-bit Dynamic Random Access Memory The Hitachi HM514280A/AL are CMOS dynamic RAM organized as 262,144-word × 18-bit. HM514280A/AL 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 HM514280A/AL offer fast page mode as a high speed access mode. Multiplexed address input permits the HM514280A/AL to be packaged in standard 400.. mil 40-pin plastic SOJ, standard 475-mil 40-pin plastic ZIP and standard 400-mil 44-pin plastic TSOPII. Ordering Information Access Type No.

This datasheet includes multiple variants, all published together in a single manufacturer document.
