Description
The R1Q3A3636 is a 1,048,576-word by 36-bit, the R1Q3A3618 is a 2,097,152-word by 18-bit, and the R1Q3A3609 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_DD power 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
• Four-tick burst for reduced address frequency
• 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: 3.0 ns (333 MHz)/3.3 ns (300 MHz)/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.
