PRELIMINARY

72-Mbit QDR-II™ SRAM 2-Word Burst

Architecture

Features

Functional Description

• Separate Independent Read and Write Data Ports

— Supports concurrent transactions

• 250-MHz clock for high bandwidth

• 2-Word Burst on all accesses

The CY7C1510AV18, CY7C1525AV18, CY7C1512AV18 and

CY7C1514AV18 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 I/O

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

• Double Data Rate (DDR) interfaces on both Read and

Write ports (data transferred at 500 MHz) @ 250 MHz

• Two input clocks (K and K) for precise DDR timing

— SRAM uses rising edges only

• Two input clocks for output data (C and C) to minimize

clock-skew and flight-time mismatches

the rising edge of the 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

(CY7C1510AV18) or 9-bit words (CY7C1525AV18) or 18-bit

words (CY7C1512AV18) or 36-bit words (CY7C1514AV18)

that burst sequentially into or out of the device. Since 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.”

• Echo clocks (CQ and CQ) simplify data capture in high

speed systems

• Single multiplexed address input bus latches address

inputs for both Read and Write ports

• Separate Port Selects for depth expansion

• Synchronous internally self-timed writes

• QDR-II operates with 1.5 cycle read latency when DLL

is enabled

• Operates like a QDR I device with 1 cycle read latency

in DLL off mode

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.

• Available in x8, x9, x18, and x36 configurations

• Full data coherency, providing most current data

• Core V_DD= 1.8V (±0.1V); I/O V_DDQ= 1.4V to V_DD

• Available in 165-ball FBGA package (15 x 17 x 1.4 mm)

• Offered in lead-free and non-lead free packages

• Variable drive HSTL output buffers

• JTAG 1149.1 compatible test access port

• Delay Lock Loop (DLL) for accurate data placement
