    摘要: A latency circuit comprises a latency control block, an internal read command generator, and a latency signal generation unit. The latency control block generates a plurality of first control clocks by delaying a delay sync signal generated based on an external clock, and generates a second control clock having a margin with respect to a read command decoded based on the delay sync signal. The internal read command generator samples the second control clock using the decoded read command and generates an internal read command based on a sampled second control clock. The latency signal generation unit generates a latency signal based on a shifting operation performed on the internal read command using the plurality of first control clocks.

    摘要: A latency control circuit includes a FIFO controller and a register unit. The FIFO controller may generate an increase signal according to an external command, and generate a decrease signal according to an internal command. The FIFO controller may also enable a depth point signal responsive to the increase signal and the decrease signal. The register unit may include n registers. The value n (rounded off) may be obtained by dividing a larger value of a maximum number of additive latencies and a maximum number of write latencies by a column cycle delay time (tCCD). The registers may store an address received with the external command responsive to the increase signal and a clock signal, and may shift either the address or a previous address to a neighboring register. The latency control circuit transmits an address stored in a register as a column address corresponding to the enabled depth point signal.
