Functional Description
The CY7C1371B/CY7C1373B is 3.3V, 512K x 36 and 1M x 18
synchronous flow-thru burst SRAMs, respectively designed to
support unlimited true back-to-back Read/Write operations
without the insertion of wait states. The CY7C1371B/
CY7C1373B is equipped with the advanced No Bus Latency鈩?/div>
(NoBL錚? logic required to enable consecutive Read/Write
operations with data being transferred on every clock cycle.
This feature dramatically improves the throughput of data
through the SRAM, especially in systems that require frequent
Write/Read transitions.The CY7C1371B/CY7C1373B is pin
compatible and functionally equivalent to ZBT devices.
All synchronous inputs pass through input registers controlled
by the rising edge of the clock.The clock input is qualified by
the Clock enable (CEN) signal, which when deasserted
suspends operation and extends the previous clock cycle.
Maximum access delay from the clock rise is 7.5 ns (117-MHz
device).
Write operations are controlled by the byte Write Selects
(BWS
a,b,c,d
for CY7C1371B and BWS
a,b
for CY7C1373B) and
a Write enable (WE) input. All writes are conducted with
on-chip synchronous self-timed Write circuitry. ZZ may be tied
to LOW if it is not used.
Synchronous Chip enables (CE

on the BGA) and an asynchronous Output enable (OE)
provide for easy bank selection and output three-state control.
In order to avoid bus contention, the output drivers are
synchronously three-stated during the data portion of a Write
sequence.
