    • A nonvolatile semiconductor memory device comprises: a memory cell array including a plurality of memory cell units each including memory cells, a plurality of bit lines, and a common source line; a sense amplifier operative to read data from a selected memory cell; a control circuit operative to control a read operation of the sense amplifier; and a cell source monitoring circuit operative to detect a voltage of the common source line, compare the detected voltage of the common source line with a reference voltage, and output a read control signal. The sense amplifier is configured to read data from the selected memory cell through at least two cycles. The control circuit is configured to perform control to determine whether the data reading is to be ended after a first reading cycle or a second reading cycle is to be carried out, based on the read control signal.
    • 非易失性半导体存储器件包括:存储单元阵列,包括多个存储单元单元,每个存储单元包括存储单元,多个位线和公共源极线; 读出放大器,用于从所选存储单元读取数据; 控制电路,用于控制读出放大器的读取操作; 以及电池源监视电路,用于检测公共源极线的电压,将公共源极线的检测电压与参考电压进行比较,并输出读取控制信号。 读出放大器被配置为通过至少两个周期从所选存储器单元读取数据。 控制电路被配置为基于读取的控制信号执行控制以确定在执行第一读取周期或第二读取周期之后是否结束数据读取。
