DESCRIPTION

The MSM518121A is an 1-Mbit CMOS multiport memory composed of a 131,072-words by 8-bit

dynamicrandomaccessmemory,RAMport,anda256-wordby8-bitstaticserialaccessmemory,

SAM port. The RAM port and SAM port operate independently and asynchronously.

The MSM518121A supports three types of operation: random access to and from the RAM port,

high speed serial access to and from the SAM port and bidirectional transfer of data between any

selectedrowintheRAMportandtheSAMport. TheRAMportandtheSAMportcanbeaccessed

independently except when data is being transferred between them internally.

FEATURES

• Single power supply of 5 V ±10% with a built-in VBB generator

• All inputs and outputs :TTL compatible

• Multiport organization

RAM port : 128K word ¥ 8 bits

SAM port : 256 word ¥ 8 bits

• RAM port

Fast page mode, Read modify write

CAS before RAS refresh, Hidden refresh

RAS only refresh, Standard write-per-bit

• SAM port

High speed serial

Read / Write capabillity

Fully static register

256 tap location

• RAM-SAM bidirectional, Read / Write / Pseudo write, Real time read transfer
