PROBLEM TO BE SOLVED: To perform correspondence for an address to a normal line and to reduce the number of coding units required for allotting by constituting a device so that a programming state of one programmable operating unit attached to each coding unit affects a function of a coding unit. SOLUTION: A memory has a coding unit FBn, and the coding unit FBn has one operating unit. The coding unit FBn corresponds one complete redundant line RCLm to one complete first line or other lines CLi conforming to an address in a first programming state of an operating unit and allots it. In a second programming state of an operating unit, the coding unit FBn corresponds only one line out of a part region of one line out of the redundant line RCLm to one correspondent part region of one line out of the first line CLi conforming to an address, and allots it.
