MSM518122, DRAM / FAST PAGE MODE TYPE

The MSM518122 is an 1-Mbit CMOS multiport DRAM composed of a 131,072-word by 8-bit dynamic RAM and a 256-word by 8-bit SAM.

Its RAM and SAM operate independently and asynchronously.

The MSM518122 supports three types of operation : random access to RAM port, high speed serial access to SAM port and

MSM518122 Features

* the 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
