Description

The IDT7054 is a high-speed 4K x 8 FourPort鈩?Static RAM designed

to be used in systems where multiple access into a common RAM is

required. This FourPort Static RAM offers increased system performance

in multiprocessor systems that have a need to communicate in real time and

also offers added benefit for high-speed systems in which multiple access

is required in the same cycle.

The IDT7054 is also designed to be used in systems where on-chip

hardware port arbitration is not needed. This part lends itself to those

systems which cannot tolerate wait states or are designed to be able to
