36-Mbit DDR-II SIO SRAM 2-Word  
Burst Architecture  
Features  
Functional Description  
• 36-Mbit density (4M x 8, 4M x 9, 2M x 18, 1M x 36)  
• 300-MHz clock for high bandwidth  
The CY7C1422V18, CY7C1429AV18, CY7C1423V18,  
CY7C1424V18 are 1.8V Synchronous Pipelined SRAMs  
equipped with DDR-II SIO (Double Data Rate Separate I/O)  
architecture. The DDR-II SIO consists of two separate ports to  
access the memory array. The Read port has dedicated Data  
outputs and the Write port has dedicated Data inputs to  
completely eliminate the need to “turn around’ the data bus  
required with common I/O devices. Access to each port is  
accomplished using a common address bus. Addresses for  
Read and Write are latched on alternate rising edges of the  
input (K) clock. Write data is registered on the rising edges of  
both K and K. Read data is driven on the rising edges of C and  
C if provided, or on the rising edge of K and K if C/C are not  
provided. Each address location is associated with two 8-bit  
words in the case of CY7C1422AV18, two 9-bit words in the  
case of CY7C1429AV18, two 18-bit words in the case of  
CY7C1423AV18, and two 36-bit words in the case of  
CY7C1424AV18, that burst sequentially into or out of the  
device.  
• 2-Word burst for reducing address bus frequency  
• Double Data Rate (DDR) interfaces  
(data transferred at 600 MHz) @ 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  
• Synchronous internally self-timed writes  
• 1.8V core power supply with HSTL inputs and outputs  
• Variable drive HSTL output buffers  
• Expanded HSTL output voltage (1.4V–VDD  
)
Asynchronous inputs include output impedance matching  
input (ZQ). Synchronous data outputs are tightly matched to  
the two output echo clocks CQ/CQ, eliminating the need for  
separately capturing data from each individual DDR-II SIO  
SRAM in the system design. Output data clocks (C/C) enable  
maximum system clocking and data synchronization flexibility.  
• Available in 165-ball FBGA package (15 x 17 x 1.4 mm)  
• Offered in both lead-free and non lead-free packages  
• JTAG 1149.1 compatible test access port  
• Delay Lock Loop (DLL) for accurate data placement  
All synchronous inputs pass through input registers controlled  
by the K/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 clock. Writes are conducted with on-chip  
synchronous self-timed write circuitry.
