Functional Description
The CY7C1303BV25 and CY7C1306BV25 are 2.5V
Synchronous Pipelined SRAMs equipped with QDR鈩?archi-
tecture. QDR 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. 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 K clock.
QDR has separate data inputs and data outputs to completely
eliminate the need to 鈥渢urn-around鈥?the data bus required with
common I/O devices. Accesses to the CY7C1303BV25/
CY7C1306BV25 Read and Write ports are completely
independent of one another. All accesses are initiated
synchronously on the rising edge of the positive input clock
(K). In order to maximize data throughput, both Read and
Write ports are equipped with Double Data Rate (DDR) inter-
faces. Therefore, data can be transferred into the device on
every rising edge of both input clocks (K and K) and out of the
device on every rising edge of the output clock (C and C, or K
and K when in single clock mode) thereby maximizing perfor-
mance while simplifying system design. Each address location
is associated with two 18-bit words (CY7C1303BV25) or two
36-bit words (CY7C1306BV25) that burst sequentially into or
out of the device.
Depth expansion is accomplished with a Port Select input for
each port. Each 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 input clocks. Writes are
conducted with on-chip synchronous self-timed write circuitry.
