128K x 36/256K x 18. The IDT71V3577/79 SRAMs contain write, data,
address and control registers. There are no registers in the data output
path (flow-through architecture). Internal logic allows the SRAM to gen-
erate a self-timed write based upon a decision which can be left until the
end of the write cycle.
system designer, as the IDT71V3577/79 can provide four cycles of data
for a single address presented to the SRAM. An internal burst address
counter accepts the first cycle address from the processor, initiating the
access sequence. The first cycle of output data will flow-through from the
array after a clock-to-data access time delay from the rising clock edge of
the same cycle. If burst mode operation is selected (ADV=LOW), the
subsequent three cycles of output data will be available to the user on the
next three rising clock edges. The order of these three addresses are
defined by the internal burst counter and the LBO input pin.
