65,536-Word ¥ 8-Bit Multiport DRAM

DESCRIPTION

The MSM54C864 is a 512Kbit CMOS multiport memory composed of a 65,536-word by 8-bit

dynamicrandomaccessmemory,RAMport,anda256-wordby8-bitstaticserialaccessmemory,

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

selectedrowintheRAMportandtheSAMport.TheRAMportandtheSAMportcanbeaccessed

independently except when data is being transferred between them internally.

FEATURES

• Single power supply of 5 V ±10% with a built-in V generator

• All inputs and outputs: TTL compatible

• Multiport organization

RAM port: 64K word ¥ 8 bits

SAM port:

• RAM port
