Abstract
A semiconductor device comprises a memory cell array comprising memory cells coupled to word lines and bit lines, a voltage generator suitable for generating a drive voltage to be applied to a selected word line, and a control logic suitable for detecting the number of pulses of a program voltage received from the memory cell array in a program operation, storing bias information corresponding to the detected number of pulses in a register, and controlling a level of the program voltage for a subsequent program operation based on the bias information.
