Product Summary
The MSM5416283-50GS-K 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 MSM5416283-50GS-K 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.
