18-Mbit DDR-II SRAM 2-Word Burst Architecture

Functional Description
• 18-Mbit density 2M x 8, 2M x 9, 1M x 18, 512K x 36
• 300-MHz clock for high bandwidth
• 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
• DDR-II operates with cycle read latency when the

DLL is enabled
• Operates like a DDR-I device with 1 cycle read latency
in DLL off mode
• 1.8V core power supply with HSTL inputs and outputs
• Variable drive HSTL output buffers
• Expanded HSTL output voltage

Configurations

CY7C1316CV18 2M x 8 CY7C1916CV18 2M x 9 CY7C1318CV18 1M x 18 CY7C1320CV18 512K x 36

The CY7C1316CV18, CY7C1916CV18, CY7C1318CV18 and CY7C1320CV18 are 1.8V Synchronous Pipelined SRAM equipped with DDR-II architecture. The DDR-II consists of an SRAM core with advanced synchronous peripheral circuitry and a 1-bit burst counter. 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 CY7C1316CV18 and two 9-bit words in the case of CY7C1916CV18 that burst sequentially into or out of the device. The burst counter always starts with a “0” internally in the case of CY7C1316CV18 and CY7C1916CV18. On CY7C1318CV18 and CY7C1320CV18, the burst counter takes in the least significant bit of the external address and bursts two 18-bit words in the case of CY7C1318CV18 and two 36-bit words in the case of CY7C1320CV18 sequentially into or out of the device.

Asynchronous inputs include output impedance matching input ZQ . Synchronous data outputs Q, sharing the same physical pins as the data inputs D are tightly matched to the two output echo clocks CQ/CQ, eliminating the need for separately capturing data from each individual DDR SRAM in the system design. Output data clocks C/C enable maximum system clocking and data synchronization flexibility.

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.
