Abstract
There is provided a semiconductor non-volatile memory including: plural memory sections, a voltage application section, and a control section that controls the voltage application section wherein the control section controlling voltage application such that, based on a value of current detected by a current detection section, in a region where the current flowing in a channel region is greater than a predetermined target value at which a amount of charge accumulated has become a specific value in at least one of a first charge accumulating section or a second charge accumulating section, when a value of current flowing in the channel region approaches a target value, a rate of increase in the charge accumulating amount per time is decreased at least once.
