MSM548263 - Multiport DRAM

Description

The MSM548263 is a 2-Mbit CMOS multiport DRAM composed of a 262,144-word by 8-bit dynamic RAM, and a 512-word by 8-bit SAM.

Its RAM and SAM operate independently and asynchronously.

Features

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

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.
