MSM54V16272 - Multiport DRAM

Description

The MSM54V16272 is a 4-Mbit CMOS multiport DRAM composed 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.

Features

  • block write and flash write functions on the RAM port, and a split data transfer capability 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. In addition to the conventional multiport DRAM operating modes, the MSM54V16272 features block write and flash write functions on the RAM port, and a split data transfer capability on the SAM port.
