Manufacturer: OKI Electric

Overview: E2L0015-17-Y1 ¡ Semiconductor ¡ Semiconductor MSM518122 131,072-Word ¥ 8-Bit Multiport DRAM This version: Jan. 1998 MSM518122 Previous version: Dec.

General Description

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 bidirectional transfer of data between any selected row in the RAM port and the SAM port.

Key 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.
