    摘要: In reading data from a memory cell, a determining circuit determines whether a received voltage value is within at least one first voltage range through a one-time read operation using a semiconductor device that senses an output current corresponding to the received voltage value. The at least one first voltage range includes a first upper limit voltage value and a first lower limit voltage value. A data value of the memory cell is set as a first data value when the received voltage value is within the specific voltage range.
