Abstract

The present disclosure relates to a sense amplifier and a sensing method thereof, a storage device and a data reading method therefor, and an electronic device. The sense amplifier (1) is configured to be connected to a bit line (BL) to read data stored in a storage unit (U). The sense amplifier (1) comprises a charge integrator (11) and a secondary amplifier (12). The charge integrator (11) is correspondingly connected to the storage unit (U) by means of the bit line (BL), and is configured to: measure the total amount of charge flowing into or out of the bit line (BL) under a stable bit line (BL) voltage, and convert the total amount of charge into a voltage as an initial read signal. The secondary amplifier (12) is connected to an output end of the charge integrator (11) and is configured to: compare the initial read signal with a reference signal so as to output a data read signal on the basis of a comparison result between the initial read signal and the reference signal.
