Description
The IDT7054 is a high-speed 4K 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 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
externally arbitrated or withstand contention when all ports simulta-
neously access the same FourPort RAM location.
The IDT7054 provides four independent ports with separate control,
