Abstract
A memory system includes a control device suitable for generating first command signals for a unit time and storing first count information corresponding to the number of times to generate the first command signals based on temperature information, in a training mode, and generating second command signals based on the first count information and second count information in a normal mode, the second count information corresponding to the number of times to generate the second command signals for the unit time, and a memory device suitable for performing an internal operation based on the first command signals and providing the control device with the temperature information when performing the internal operation, in the training mode, and performing an internal operation based on the second command signals in the normal mode.
Claims16
A memory system comprising:
- a control device suitable for generating first command signals for a unit time and storing first count information corresponding to the number of times to generate the first command signals based on temperature information, in a training mode, and generating second command signals based on the first count information and second count information in a normal mode, the second count information corresponding to the number of times to generate the second command signals for the unit time;
- and
- a memory device suitable for performing an internal operation based on the first command signals and providing the control device with the temperature information when performing the internal operation, in the training mode, and performing an internal operation based on the second command signals in the normal mode.
An operating method of a memory system comprising:
- sensing a temperature of a memory device when the memory device performs an internal operation based on first command signals for a unit time, in a training mode;
- storing the number of times to generate the first command signals according to the temperature, in the training mode;
- and
- monitoring heat generation of the memory device based on the number of times to generate the first command signals according to the temperature when the memory device performs an internal operation based on second command signals for the unit time, in a normal mode.
A memory system comprising:
- a memory device including a temperature sensor;
- and
- a control device suitable for:
- providing training commands with the memory device in a training mode;
- monitoring a temperature of the memory device from the temperature sensor;
- when the monitored temperature is equal to a threshold temperature, determining the number of provided training commands;
- providing normal commands with the memory device in a normal mode;
- and
- when the number of the normal commands is equal to the number of provided training commands, stopping the providing of the normal commands.
