Patent ID: 11862277
Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 6:
7. A deterioration detection device comprising:
a mode selector configured to output a mode selection signal setting an operating mode of the deterioration detection device to a first operating mode or a second operating mode, in response to a first external command;
a comparator configured to receive an internal operating condition of a memory device and a target condition in the first operating mode, and to compare the internal operating condition with the target condition to output a result of the comparison as a first current path selection signal;
a storage including a first current path and a second current path, and configured to selectively apply a current to one current path among the first current path and the second current path response to the first current path selection signal; and
a delay detection circuit configured to detect deterioration accumulated in the selected current path,
wherein the internal operating condition of the memory device includes an internal temperature of the memory device.
