MSM514252A - DRAM / FAST PAGE MODE TYPE
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
