Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 13:
14. A deterioration detection device comprising:
a plurality of storages each including a first current path and a second current path to which a current is applied in a first operating mode;
a plurality of storage input control circuits each configured to select a current path of each of the plurality of storages, to which the current is to be applied, among the first current path and the second current path, in the first operating mode;
a storage output control circuit configured to select a storage among the plurality of storages, and measure deterioration of the selected storage in a second operating mode; and
a delay detection circuit configured to detect deterioration accumulated in the current path of the selected storage in the second operating mode,
wherein each of the plurality of storage input control circuits is further configured to compare an internal operating condition of memory device with a target condition, and select one of the first current path and the second current path based on a result of the comparison, and
wherein the internal operating condition of the memory device includes an internal temperature of the memory device.
