Original Abstract Submitted
A semiconductor storage device includes a memory cell and a control circuit. In an overall read operation, the control circuit performs a first read operation to detect a first voltage and determine first data from the detected first voltage, writes second data to the memory cell, performs a second read operation to detect a second voltage and determine the second data from the detected second voltage, and compares the first data and the second data based on the first voltage and the second voltage to determine a value of the first data. When the first data and the second data are different, the control circuit performs a sequence of operations that includes a second write operation to write the first data and a verify read operation. Based on third data detected by the verify read operation, the control circuit ends the overall read operation or repeats the sequence of operations.
