Claim:
1. An apparatus comprising a semiconductor device, the apparatus comprising: a plurality of elements including a first element and a second element; a volatile memory configured to store first information corresponding to the first element; a non-volatile memory configured to store second information associated with the first element; and a logic circuit configured to receive one of the first and second information as an input signal from the volatile memory and the non-volatile memory, respectively and configured to perform a replacement operation of selecting the second element instead of the first element based, at least in part, on the input signal, wherein, responsive to a control signal being a first state, the replacement operation is performed based, at least in part, on the first information stored in the volatile memory, and wherein, responsive to the control signal being a second state, the replacement operation is performed based, at least in part, on the second information stored in the non-volatile memory.
