Circuit and method for data processing, and semiconductor memory

A method for data processing, applied to a circuit for data processing comprising a receiving circuit, a first power supply circuit and a processing circuit, the method comprising:

• receiving, by the receiving circuit, a data signal, and determining a first node signal according to the data signal;
• receiving, by the first power supply circuit, an enable signal, and controlling, in a case that the enable signal is in a valid state, the processing circuit to be in an operating state;
• and
• outputting, by the processing circuit in a case of being in the operating state, a target data signal according to the first node signal.

A semiconductor memory, comprising:

• a circuit for data processing,
• wherein the circuit for data processing comprises:
• a receiving circuit, a first power supply circuit and a processing circuit, wherein
• the receiving circuit is configured to receive a data signal and determine a first node signal according to the data signal;
• the first power supply circuit is configured to receive an enable signal, and control, in a case that the enable signal is in a valid state, the processing circuit to be in an operating state;
• and
• the processing circuit is configured to output, in a case of being in the operating state, a target data signal according to the first node signal.
