MSM54V16273 Multiport DRAM

The MSM54V16273 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 bidire.

MSM54V16273 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. FEATURES

* Single power supply: 3.3 V ± 0.3 V

* RAS on
