  • Patent number: 9224487
    Abstract: A semiconductor memory includes a sense amplifier which operates in response to activation of a sense amplifier enable signal and determines logic held in a nonvolatile memory cell according to a voltage of a bit line, the voltage varying with a cell current flowing through a real cell transistor, a replica cell transistor coupled in series between a first node and a ground line, and a timing generation unit. The timing generation unit activates the sense amplifier enable signal when the first node coupled to the ground line via the replica cell transistor changes from a high level to a low level. The replica cell transistor includes a control gate receiving a constant voltage and a floating gate coupled to the control gate. Thus, the activation timing of the sense amplifier can be optimally set in accordance with the electric characteristic of the memory cell.
