Description
The IDT7052 is a high-speed 2K x 8 FourPort™ 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 IDT7052 is also designed to be used in systems where on-chip
hardware port arbitration is not needed. This part lends itself to those
