The present invention provides a semiconductor device and a method for controlling a semiconductor device having a memory cell array having a plurality of nonvolatile memory cells, the method including detecting the number of bits to be written as division data that is divided from data to be programmed into the memory cell array, comparing the number of bits with a predetermined number of bits, inverting or not inverting the division data to produce inversion data in accordance with a result of comparing the number of bits with the predetermined number of bits, and programming the inversion data into the memory cell array. The method further includes detecting the number of bits to be written as next division data and comparing the number of bits of next division data with the predetermined number of bits, while concurrently programming the inversion data into the memory cell array.
