262,144-Word ¥ 16-Bit Multiport DRAM

DESCRIPTION

The MSM54V16283 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

SAMport.InadditiontotheconventionalmultiportDRAMoperatingmodes,theMSM54V16283

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
