Abstract
A memory device includes a memory region, and a setting circuit suitable for changing setting information based on a temperature information signal so that the memory region operates according to a first condition at pseudo cryogenic temperature, and operates according to a second condition at room temperature.
Claims20
A memory device comprising:
- a memory region;
- and
- a setting circuit suitable for changing setting information based on a temperature information signal so that the memory region operates according to a first condition at pseudo cryogenic temperature, and operates according to a second condition at room temperature.
A memory device comprising:
- a setting circuit suitable for generating first setting information as memory setting information at pseudo cryogenic temperature, and generating second setting information as the memory setting information at room temperature, based on a temperature information signal;
- a refresh control circuit suitable for generating one or more refresh control signals corresponding to any one of the first and second setting information based on the memory setting information and a refresh signal;
- and
- a memory region suitable for performing a refresh operation according to a first condition corresponding to the first setting information or performing a refresh operation according to a second condition corresponding to the second setting information, based on the refresh control signals and an address signal.
