Abstract
A pipe latch circuit includes a division unit configured to output a division signal, a multiplexing unit configured to multiplex a plurality of source signals according to periods determined by the division signal and generate a plurality of pipe input control signals, and a pipe latch unit configured to sequentially latch a plurality of data signals in response to the pipe input control signals, wherein the source signals are sequentially activated in response to an input/output (I/O) strobe signal.
Claims15
A pipe latch circuit, comprising:
- a division unit configured to output a division signal;
- a multiplexing unit configured to multiplex a plurality of source signals in response to the division signal and generate a plurality of pipe input control signals;
- and
- a pipe latch unit configured to sequentially latch a plurality of data signals in response to the pipe input control signals,
- wherein the source signals are sequentially activated in response to an input/output (I/O) strobe signal.

An operation method of a pipe latch circuit, comprising:
- outputting a first count value, generated by counting an I/O strobe signal during a first period where a division signal has a first logic level, as a plurality of first pipe input control signals;
- outputting a second count value, generated by counting the I/O strobe signal during a second period where the division signal has a second logic level, as a plurality of second pipe input control signals;
- and
- sequentially latching a plurality of data signals in response to the first and second pipe input control signals.
