Abstract
A system includes a semiconductor device configured to store data and a controller communicatively coupled to the semiconductor device. The semiconductor device and the controller are configured to; in response to determining that particular data stored in the semiconductor device satisfies a reliability condition, obtain first readout data by reading the particular data at a first read voltage, and obtain second readout data by reading the particular data at a second read voltage. The second read voltage is different from the first read voltage. The semiconductor device and the controller are configured to compare the first readout data and the second readout data and obtain a comparison result; and, based on the comparison result, determine whether to perform an error correction process on the particular data.
