    • To provide a current sensing circuit that detects a difference between a cell current and a reference current. The current sensing circuit includes: current mirror circuits of which the input terminal is connected with a reference current source; a differential amplifier of which the one input terminal is supplied with a potential of an electrical connection point between an output terminal of the current mirror circuit and a memory cell and of which the other input terminal is supplied with a reference potential; and an equalizing circuit that short-circuits the both input terminals of the differential amplifier in response to an equalizing signal. Thereby, the both input terminals can be kept at the same potential immediately before a sensing operation starts, and thus, even when the cell current is weak, a highly sensitive sensing operation can be performed at high speed.
    • 提供检测电池电流和参考电流之间的差异的电流感测电路。 电流检测电路包括:输入端与参考电流源连接的电流镜电路; 其中一个输入端被提供在电流镜电路的输出端和存储单元之间的电连接点的电位并且另一输入端被提供有参考电位的差分放大器; 以及均衡电路,其响应于均衡信号使差分放大器的两个输入端短路。 因此,两个输入端子可以在感测操作开始之前保持在相同的电位,因此,即使电池电流较弱,也可以高速执行高灵敏度的感测操作。
