MSM54C864, Multiport DRAM

The MSM54C864 is a 512Kbit CMOS multiport memory composed of a 65,536-word by 8-bit dynamic random access memory, RAM port, and a 256-word by 8-bit static serial access memory, SAM port.

The RAM port and SAM port operate independently and asynchronously.

The MSM54C864 supports three types of operati
