MSM54C864  
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  
BB  
• All inputs and outputs: TTL compatible  
• Multiport organization  
RAM port: 64K word ¥ 8 bits  
SAM port:  
• RAM port  
256 word ¥ 8 bits  
Fast page mode, Read-modify-write  
CAS before RAS refresh, Hidden refresh  
RAS only refresh, Standard write-per-bit  
• SAM port  
High speed serial  
Read / Write capability  
Fully static register  
256 tap location  
• RAM-SAM bidirectional, Read / Write / Pseudo write, Real time read transfer  
• Refresh : 256 cycles/4 ms
