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.
