QDR II architecture consists of two separate ports: SRAM uses rising edges only the read port and the write port to access the memory array. The read port has dedicated data outputs to support read operations Two input clocks for output data (C and C) to minimize clock and the write port has dedicated data inputs to support write skew and flight time mismatches operations. QDR II architecture has separate data inputs and data outputs to completely eliminate the need to turn around the Echo clocks (CQ and CQ) simplify data capture in high-speed data bus that exists with common I/O devices. Access to each systems port is through a common address bus. Addresses for read and Single multiplexed address input bus latches address inputs write addresses are latched on alternate rising edges of the input for both read and write ports (K) clock. Accesses to the QDR II read and write ports are completely independent of one another. To maximize data Separate port selects for depth expansion throughput, both read and write ports are equipped with DDR Synchronous internally self-timed writes interfaces. Each address location is associated with two 9-bit words (CY7C1625KV18), 18-bit words (CY7C1612KV18), or Quad data rate (QDR ) II operates with 1.5-cycle read latency 36-bit words (CY7C1614KV18) that burst sequentially into or out when DOFF is asserted high of the device. Because data can be transferred into and out of the device on every rising edge of both input clocks (K and K and Operates similar to QDR I device with 1 cycle read latency when C and C), memory bandwidth is maximized while simplifying DOFF is asserted low system design by eliminating bus turnarounds. Available in 9, 18, and 36 configurations Depth expansion is accomplished with port selects, which Full data coherency, providing most current data enables each port to operate independently. All synchronous inputs pass through input registers controlled by Core V = 1.8 V ( 0.1 V) I/O V = 1.4 V to V DD DDQ DD the K or K input clocks. All data outputs pass through output Supports both 1.5 V and 1.8 V I/O supply registers controlled by the C or C (or K or K in a single clock Available in 165-ball fine-pitch ball grid array (FBGA) package domain) input clocks. Writes are conducted with on-chip (15 17 1.4 mm) synchronous self-timed write circuitry. Offered in both Pb-free and non Pb-free packages For a complete list of related documentation, click here.
