MSM5416273 Datasheet Multiport Dram

Manufacturer: OKI Electric

Overview: E2L0021-17-Y1 .. ¡ Semiconductor ¡ Semiconductor MSM5416273 262,144-Word ¥ 16-Bit Multiport DRAM This version: Jan. 1998 MSM5416273 Previous version: Dec.

General Description

The MSM5416273 is a 4-Mbit CMOS multiport DRAM posed of a 262,144-word by 16-bit dynamic RAM, and a 512-word by 16-bit SAM.

Its RAM and SAM operate independently and asynchronously.

It supports three types of operations: random access to RAM port, high speed serial access to SAM port, and bidirectional transfer of data between any selected row in the RAM port and the SAM port.

Key Features

  • block write, flash write functions, extended page mode on the RAM port, a split data transfer capability, and programmable stops on the SAM port. The SAM port requires no refresh operation because it uses static CMOS flip-flops.
