MSM54C865  
65,536-Word ¥ 8-Bit Multiport DRAM  
DESCRIPTION  
The MSM54C865 is a 512Kbit CMOS multiport DRAM composed of a 65,536-word by 8-bit  
dynamic RAM and a 256-word by 8-bit SAM. Its RAM and SAM operate independently and  
asynchronously.  
TheMSM54C865supportsthreetypesofoperaton:randomaccesstoRAMport,highspeedserial  
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  
MSM54C865 features the block write and flash write functions on the RAM port and a split data  
transfer capability on the SAM port. The SAM port requires no refresh operation because it uses  
static CMOS flip-flops.  
FEATURES  
• Single power supply: 5 V ±10%  
• Full TTL compatibility  
• Multiport organization  
RAM : 64K word ¥ 8 bits  
SAM : 256 word ¥ 8 bits  
• Fast page mode

RAS only refresh  
CAS before RAS refresh  
• Hidden refresh  
• Serial read/write  
• 256 tap location  
• Bidirectional data transfer  
• Split transfer  
• Masked write transfer  
• Refresh :256 cycles/4 ms  
• Package options:
