A memory includes: memory devices that each store data of one bit; and a read unit that, by using one predetermined memory device of the memory devices that are included in a memory block having a predetermined unit number of the memory devices as an inversion flag device, reads out data of (the predetermined unit number −1) bits that is written in the other memory devices with the bits being inverted in a case where the data of one bit written in the inversion flag device is a first value representing any one of “0” and “1” and directly reads out the data of (the predetermined unit number −1) bits that is written in the other memory devices in a case where the data of one bit written in the inversion flag device is a second value other than the first value.
