    • A readout circuit has a sense amplifier to compare a cell current which changes according to whether a memory cell is on or off with a reference current, to output a comparison signal of a first logic upon detecting that the cell current is smaller than the reference current, and to output a comparison signal of a second logic upon detecting that the cell current is greater than the reference current, the readout circuit outputting a data output signal depending upon an output of the sense amplifier. The reference current is set to be greater than a middle value between a first cell current which flows when the memory cell is in an off-state and a second cell current which flows when the memory cell is in an on-state and which is greater than the first cell current, and to be smaller than the second cell current. Unless the sense amplifier detects that the cell current is smaller than the reference current as a result of comparison made between the cell current and the reference current, the sense amplifier outputs the comparison signal of the second logic regardless of whether the sense amplifier detects that the cell current is greater than the reference current.
    • 读出电路具有读出放大器,用于将根据存储器单元是否导通的单元电流与参考电流进行比较,以在检测到单元电流小于参考电流时输出第一逻辑的比较信号 并且在检测到单元电流大于参考电流时输出第二逻辑的比较信号,读出电路根据读出放大器的输出输出数据输出信号。 参考电流被设定为大于当存储器单元处于关闭状态时流动的第一单电池电流与当存储单元处于导通状态时流动的第二单元电流之间的中间值,并且大于 比第一电池电流小,并且小于第二电池电流。 作为单元电流和参考电流之间进行比较的结果,除非读出放大器检测到单元电流小于参考电流,否则读出放大器输出第二逻辑的比较信号,而不管读出放大器是否检测到 电池电流大于参考电流。
