Abstract
A memory apparatus includes a control circuit, a plurality of memory arrays, each of which contains a plurality of memory cells, and a current detecting circuit. The current detecting circuit measures a quantity of a current of a first memory array. A redundancy information is changed when the quantity of the current of the first memory array is over a first current quantity detected by the current detecting circuit. The control circuit controls an access to the memory arrays, and changes the access to the first memory array to a second memory array in accordance with the redundancy information.
