Architecture

Features

Functional Description

• Separate Independent Read and Write Data Ports

— Supports concurrent transactions

The CY7C1511V18, CY7C1526V18, CY7C1513V18, and

CY7C1515V18 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. 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. 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 four 8-bit words (CY7C1511V18) or 9-bit

words (CY7C1526V18) or 18-bit words (CY7C1513V18) or

36-bit words (CY7C1515V18) 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 simpli-

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

• 300-MHz Clock for High Bandwidth

• 4-Word Burst for reducing address bus frequency

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

Write Ports (data transferred at 600 MHz) at 300 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

• 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

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

• Full data coherency providing most current data

• Core V_DD= 1.8 (±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 both lead-free and non-lead free packages

• Variable drive HSTL output buffers

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.

• JTAG 1149.1 Compatible test access port

• Delay Lock Loop (DLL) for accurate data placement
