    • According to one embodiment, a semiconductor memory device includes a memory cell array and a control circuit. The memory cell array is composed of a plurality of memory cells arranged in a matrix pattern. The control circuit sets a first flag data in a second memory cell in order to write data to a plurality of first memory cells of memory cell array, the second memory cell having been selected at the same time as the first memory cells, determines whether the first flag data is set in the second memory cell before data is read from the first memory cells, and reads no data from the first memory cells and outputs data of first logic level if the first flag data is not set in the second memory cell, and reads data from the first memory cells if the first flag data is set in the second memory cell.
    • 根据一个实施例,半导体存储器件包括存储单元阵列和控制电路。 存储单元阵列由以矩阵图案排列的多个存储单元组成。 控制电路在第二存储器单元中设置第一标志数据,以便将数据写入存储单元阵列的多个第一存储单元,第二存储单元已经与第一存储器单元同时被选择, 在从第一存储器单元读取数据之前,在第二存储单元中设置第一标志数据,并且如果第一标志数据未被设置在第二存储器单元中,则不从第一存储器单元读取数据并输出第一逻辑电平的数据, 并且如果第一标志数据被设置在第二存储器单元中,则从第一存储器单元读取数据。
