Functional Description
[1]
The CY7C1371D/CY7C1373D is a 3.3V, 512K x 36/1M x 18
Synchronous flow through Burst SRAM designed specifically
to support unlimited true back-to-back Read/Write operations
with no wait state insertion. The CY7C1371D/CY7C1373D is
equipped with the advanced No Bus Latency (NoBL) 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.
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 6.5 ns (133-MHz
device).
Write operations are controlled by the two or four Byte Write
Select (BW
X
) and a Write Enable (WE) input. All writes are
conducted with on-chip synchronous self-timed write circuitry.
Three synchronous Chip Enables (CE
1
, CE
2
, CE
3
) and an
asynchronous Output Enable (OE
) provide for easy bank
selection and output tri-state control. To avoid bus contention,
the output drivers are synchronously tri-stated during the data
portion of a write sequence.
