8-Bit Multiport DRAM
This version: Jan. 1998
MSM54C864
Previous version: Dec. 1996
DESCRIPTION
The MSM54C864 is a 512Kbit CMOS multiport memory composed of a 65,536-word by 8-bit
dynamic random access memory, RAM port, and a 256-word by 8-bit static serial access memory,
SAM port. The RAM port and SAM port operate independently and asynchronously.
The MSM54C864 supports three types of operation : random access to and from the RAM port,
high speed serial access to and from the SAM port and bidirectional transfer of data between any
selected row in the RAM port and the SAM port. The RAM port and the SAM port can be accessed
independently except when data is being transferred between them internally.
FEATURES
• Single power supply of 5 V
