Data storage circuit and control method thereof, and storage apparatus

A method for controlling data storage, applied to a data storage circuit, the data storage circuit comprising a sense amplifier array and a first storage array positioned on a side of the sense amplifier array, the sense amplifier array being electrically connected to a main bit line, the first storage array comprising a plurality of first sub storage arrays, each of the plurality of first sub storage arrays comprising a plurality of first sub bit lines and a plurality of first selector switches, the plurality of first sub bit lines being electrically connected to the main bit line via the plurality of first selector switches, the method comprising:

• controlling a given one of the plurality of first selector switches corresponding to a selected one of the plurality of first sub storage arrays to be turned on to electrically connect the plurality of first sub bit lines and the main bit line, and controlling a given one of the plurality of first selector switches corresponding to an unselected one of the plurality of first sub storage arrays to be turned off;
• and
• controlling the sense amplifier array to be in an amplification stage to amplify a signal of the main bit line, wherein a start moment of the amplification stage is later than a start moment of turn-on of the given first selector switch.
