MSM5416272  
262,144-Word ¥ 16-Bit Multiport DRAM  
DESCRIPTION  
The MSM5416272 is a 4-Mbit CMOS multiport DRAM composed of a 262,144-word by 16-bit  
dynamic RAM, and a 512-word by 16-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 MSM5416272  
features 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 : 256K word ¥ 16 bits  
SAM : 512 word ¥ 16 bits
