    Abstract: The invention provides a sense amplifier circuit, a method for operating same, and a fabrication method for same. The sense amplifier circuit includes: an amplifier electrically connected to a memory cell of a semiconductor memory; and a pre-amplifier located between the amplifier and the memory cell, where the pre-amplifier is configured to pre-amplify an electrical signal transmitted from the memory cell to the amplifier. In this way, the pre-amplifier is provided between the amplifier and the memory cell, such that the electrical signal stored in the semiconductor memory can be output after two stages of amplification by the pre-amplifier and the amplifier, thereby avoiding the problem that the electrical signal output from the memory cell cannot be accurately received and output in a case of a small sense margin of a signal of the sense amplifier.
