Claim Text:
1. A storage controlling apparatus, comprising: a decision portion configured to decide whether or not a number of bits of a specific value from between binary values is greater than a reference value at one of two portions 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, wherein the reference value is the number of bits of the specific value at the other one of the two portions; and a write side outputting portion configured to output, when it is decided that the number of bits is greater than the reference value, the input data, wherein the one portion, but not all, of which is inverted as write data to the memory cell together with the decision data, wherein the decision portion is further configured to decide whether a first count of the number of bits of the specific value in odd-numbered bit columns of the input data is greater than a second count of the number of bits of the specific value in even-numbered bit columns of the input data and to generate the decision data indicative of the result of the decision.
