摘要: A nonvolatile semiconductor memory recovers variation in the threshold of a memory cell due to disturbance related to a word line. The nonvolatile memory continuously performs many writing operations without carrying out single-sector erasing after each writing operation, performing the additional writing operations quicker than the usual writing operation, and lightening the burden imposed on software for use in additional writing. The data stored in a designated sector is read out before being saved in a register, and the selected sector is subjected to single-sector erasing when a predetermined command is given. Then write expected value data is formed from the saved data and data to be additionally written, completing the writing operation.
