Description

The R1Q2A3636B is a 1,048,576-word by 36-bit, the R1Q2A3618B is a 2,097,152-word by 18-bit, and the

R1Q2A3609B is a 4,194,304-word by 9-bit synchronous quad data rate static RAM fabricated with advanced CMOS

technology using full CMOS six-transistor memory cell. It integrates unique synchronous peripheral circuitry and a

burst counter. All input registers controlled by an input clock pair (K and /K) and are latched on the positive edge of K

and /K. These products are suitable for applications which require synchronous operation, high speed, low voltage, high

density and wide bit configuration. These products are packaged in 165-pin plastic FBGA package.

Features

•

1.8 V 0.1 V power supply for core (V_DD

1.4 V to V_DDpower supply for I/O (V_DDQ

DLL circuitry for wide output data valid window and future frequency scaling

Separate independent read and write data ports with concurrent transactions

100% bus utilization DDR read and write operation

Two-tick burst for low DDR transaction size

)

Two input clocks (K and /K) for precise DDR timing at clock rising edges only

Two output clocks (C and /C) for precise flight time and clock skew matching-clock and data delivered together to

receiving device

•

Internally self-timed write control

Clock-stop capability with µs restart

User programmable impedance output

Fast clock cycle time: 4.0 ns (250 MHz)/5.0 ns (200 MHz)/6.0 ns (167 MHz)

Simple control logic for easy depth expansion

JTAG boundary scan

Notes: QDR RAMs and Quad Data Rate RAMs comprise a new family of products developed by Cypress

Semiconductor, IDT, NEC, Samsung, and Renesas Technology Corp.
