16-Bit Multiport DRAM
DESCRIPTION
The MSM5416272 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 MSM5416272
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.
