MSM5416273

262,144-Word

¥ 16-Bit Multiport DRAM

DESCRIPTION

The MSM5416273 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.

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 MSM5416273

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.
