8-Bit Multiport DRAM
This version: Jan. 1998
MSM548263
Previous version: Dec. 1996
DESCRIPTION
The MSM548263 is a 2-Mbit CMOS multiport DRAM composed of a 262,144-word by 8-bit
dynamic RAM, and a 512-word by 8-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 MSM548263
features block write, flash write functions and extended page mode on the RAM port and a split
data transfer capability, programmable stops on the SAM port. The SAM port requires no refresh
operation because it uses static CMOS flip-flops.
