Abstract
A pipe latch circuit includes a data latch circuit configured to latch an input data based on an input control signal and output the latched input data as a latch data based on an output control signal, a sense amplification circuit configured to sense and amplify the latch data based on a sum output control signal, and a data driving circuit configured to drive an output data from the latch data based on the sum output control signal.
Claims20
A pipe latch circuit comprising;
- a data latch circuit configured to latch an input data based on an input control signal and output the latched input data as a latch data based on an output control signal;
- a sense amplification circuit configured to sense and amplify the latch data based on a sum output control signal;
- and
- a data driving circuit configured to drive an output data from the latch data based on the sum output control signal,
- wherein the sum output control signal is generated from the output control signal.

A pipe latch circuit comprising:
- a first data latch configured to latch an input data to a first node when a pulse of a first bit of an input control signal is generated and output the input data that is latched to the first node as a latch data when a pulse of a first bit of an output control signal is generated;
- a second data latch configured to latch the input data to a second node when a pulse of a second bit of the input control signal is generated and output the input data that is latched to the second node as the latch data when a pulse of a second bit of the output control signal is generated;
- and
- a sense amplification circuit configured to sense and amplify the latch data to drive an output data based on a sum output control signal, wherein the sum output control signal is generated from the output control signal.

A method of executing consecutive data output operations comprising:
- latching an input data and an inverted input data based on an input control signal, outputting the latched input data as a latch data based on an output control signal, and outputting the latched inverted input data as an inverted latch data;
- sensing and amplifying the latch data and the inverted latch data based on a sum output control signal;
- and
- driving an output data based on the latch data, the inverted latch data, and the sum output control signal,
- wherein the sum output control signal is generated from the output control signal.
