MSM514252A Overview
The MSM514252A is an 1-Mbit CMOS multiport DRAM posed 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.
