Features, Applications

This version: Jan. 1998 MSM5416283 Previous version: Dec. 1996


The a 4-Mbit CMOS multiport DRAM composed by 16-bit dynamic RAM, and 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 MSM5416283 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.
