4-Bit Multiport DRAM
This version: Jan. 1998
MSM514252A
Previous version: Dec. 1996
DESCRIPTION
The MSM514252A is an 1-Mbit CMOS multiport DRAM composed of a 262,144-word by 4-bit
dynamic RAM, and a 512-word by 4-bit static serial access memory, SAM port. The RAM port
and SAM port operate independently and asynchronously.
The MSM514252A supports three types of operations: 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
