18-Mbit QDR™-II+ SRAM 4-Word Burst

Architecture (2.0 Cycle Read Latency)

Features

Functional Description

■ Separate Independent read and write data ports

❐ Supports concurrent transactions

■ 300 MHz to 375 MHz clock for high bandwidth

The CY7C1141V18, CY7C1156V18, CY7C1143V18, and

CY7C1145V18 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

■ 4-Word Burst for reducing address bus frequency

■ DoubleDataRate(DDR)interfacesonbothreadandwriteports

(data transferred at 750 MHz) at 375 MHz

■ Read latency of 2.0 clock cycles

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

❐ SRAM uses rising edges only

■ Echo clocks (CQ and CQ) simplify data capture in high speed

port is accomplished through

a common address bus.

Addresses for read and write addresses are latched on alternate

rising edges of the input (K) clock. Accesses to the QDR-II+ read

and write ports are completely independent of one another. To

maximize data throughput, both read and write ports are

equipped with Double Data Rate (DDR) interfaces. Each

address location is associated with four 8-bit words

(CY7C1141V18), or 9-bit words (CY7C1156V18), or 18-bit words

(CY7C1143V18), or 36-bit words (CY7C1145V18) that burst

sequentially into or out of the device. Because data can be trans-

ferred into and out of the device on every rising edge of both input

clocks K and K, memory bandwidth is maximized while simpli-

fying system design by eliminating bus “turn-arounds”.

systems

■ Single multiplexed address input bus latches address inputs

for both read and write ports

■ Separate Port Selects for depth expansion

■ Data valid pin (QVLD) to indicate valid data on the output

■ Synchronous internally self-timed writes

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

■ Full data coherency providing most current data

[1]

■ Core V_DD= 1.8V ± 0.1V; IO V_DDQ= 1.4V to V_DD

Depth expansion is accomplished with Port Selects for each port.

Port Selects enable each port to operate independently.

■ Available in 165-Ball FBGA package (13 x 15 x 1.4 mm)

■ Offered in both Pb-free and non Pb-free packages

■ Variable drive HSTL output buffers

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 K or K input clocks. Writes are

conducted with on-chip synchronous self-timed write circuitry.

■ JTAG 1149.1 compatible test access port

■ Delay Lock Loop (DLL) for accurate data placement

Configurations

With Read Cycle Latency of 2.0 cycles:

CY7C1141V18 – 2M x 8

CY7C1156V18 – 2M x 9

CY7C1143V18 – 1M x 18

CY7C1145V18 – 512K x 36
