Functional Description
The CY7C1410AV18, CY7C1425AV18, CY7C1412AV18, and
CY7C1414AV18 are 1.8V Synchronous Pipelined SRAMs,
equipped with QDR™-II architecture. QDR-II architecture
consists of two separate ports to access the memory array.
The Read port has dedicated Data Outputs to support Read
operations and the Write Port has dedicated Data Inputs to
support Write operations. QDR-II architecture has separate
data inputs and data outputs to completely eliminate the need
to “turn-around” the data bus required with common IO
devices. Access to each port is accomplished through a
common address bus. The Read address is latched on the
rising edge of the K clock and the Write address is latched on
the rising edge of the K clock. Accesses to the QDR-II Read
and Write ports are completely independent of one another. In
order to maximize data throughput, both Read and Write ports
are equipped with Double Data Rate (DDR) interfaces. Each
address location is associated with two 8-bit words
(CY7C1410AV18) or 9-bit words (CY7C1425AV18) or 18-bit
words (CY7C1412AV18) or 36-bit words (CY7C1414AV18)
that burst sequentially into or out of the device. While data can
be transferred into and out of the device on every rising edge
of both input clocks (K and K and C and C), memory bandwidth
is maximized while simplifying system design by eliminating
bus “turn-arounds.”
Depth expansion is accomplished with Port Selects for each
port. Port selects allow each port to operate independently.
All synchronous inputs pass through input registers controlled
by the K or K input clocks. All data outputs pass through output
registers controlled by the C or C (or K or K in a single clock
domain) input clocks. Writes are conducted with on-chip
synchronous self timed write circuitry.
