Abstract
According to one aspect of the present disclosure, a method of voltage calibration is provided. The method may include detecting a target temperature of a memory cell array. The method may include performing a read operation on the memory cell array at each of multiple candidate times with a standard read voltage. The method may include obtaining a number of target read fail bits. Each of the candidate times may correspond to one of the number of the target read fail bits. The method may include determining a target read voltage offset parameter according to the target temperature, the number of the target read fail bits, the candidate time, and a stored target offset function. The method may include calibrating the read voltage of the read operation on the memory cell array with the target read voltage offset parameter.
