Oki Electric Industry MSM54V16282
The MSM54V16282 is a 4-Mbit CMOS multiport DRAM composed of a 262,144-word by 16-bit dynamic RAM, and a 512-word by 16-bit SAM. Its RAM and SAM operate independently and asynchronously. It supports three types of operations: 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.| Part No. | MSM54V16282 |

DESCRIPTION
In addition to the conventional multiport DRAM operating modes, the MSM54V16282 features 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
