Read Operations The SRAM operates continuously in a burst-of-four mode. Read cycles are started by registering R# in active low state at the rising edge of the K clock. R# can be activated every other cycle because two full cycles are required to complete the burst of four in DDR mode. A set of free-running echo clocks, CQ and CQ#, are produced internally with timings identical to the data-outs. The echo clocks can be used as data capture clocks by the receiver device. The data corresponding to the first address is clocked two cycles later by the rising edge of the K clock. The data corresponding to the second burst is clocked two and half cycles later by the following rising edge of the K# clock. The third data-out is clocked by the subsequent rising edge of the K clock, and the fourth data-out is clocked by the subsequent rising edge of the K# clock. A NOP operation (R# is high) does not terminate the previous read. Write Operations Write operations
