Abstract
A memory system may include a memory device comprising a plurality of memory blocks and a controller suitable for controlling an operation of the memory device. The controller may perform a fake operation on a predetermined memory block not used to store data when a temperature of the memory device is in a low temperature range.
Claims20
A memory system comprising:
- a memory device comprising a plurality of memory blocks;
- and
- a controller suitable for controlling an operation of the memory device,
- wherein the controller performs a fake operation on a bad block that is determined to be no longer used to store data when a temperature of the memory device is in a low temperature range.

A method of controlling a temperature, by a memory system, the memory system comprising a memory device including a plurality of memory blocks and a controller suitable for controlling the memory device, and the method comprising:
- detecting a temperature of the memory device;
- and
- performing a fake operation on a bad block that is determined to be no longer used to store data when the detected temperature of the memory device is in a low temperature range.
A memory system comprising:
- a memory device comprising a plurality of memory blocks;
- and
- a controller suitable for controlling an operation of the memory device,
- wherein the controller performs a fake operation on a set memory block not used to store data when a temperature of the memory device is in a low temperature range,
- wherein the controller performs a first background operation according to a first execution condition when the temperature is in a normal temperature range, performs a second background operation according to a second execution condition when the temperature is in the low temperature range, and performs a third background operation according to a third execution condition when the temperature is in a high temperature range, and
- wherein the second execution condition has more execution targets and a shorter execution period than the first execution condition.
