Abstract:
Disclosed herein is a storage controlling apparatus including: a decision portion configured to decide whether or not a bit number of a specific value from between binary values is greater than a reference value in at least part of input data to a memory cell, which executes rewriting to one of the binary values and rewriting to the other one of the binary values in order in a writing process, to generate decision data indicative of a result of the decision; and a write side outputting portion configured to output, when it is decided that the bit number is greater than the reference value, the input data at least part of which is inverted as write data to the memory cell together with the decision data.
