  • Training method of memory device and electronic device and electronic system including the same
    Patent number: 11461113
    Abstract: An electronic device includes: a memory device; a nonvolatile memory configured to store a plurality of first configuration parameters respectively corresponding to operating voltages of the memory device and a plurality of second configuration parameters respectively corresponding to operating temperatures of the memory device; and a memory controller configured to: determine a value of a third configuration parameter corresponding to an operating voltage of the memory device among the plurality of first configuration parameters stored in the nonvolatile memory without performing a training operation, determine a value of a fourth configuration parameter corresponding to an operating temperature of the memory device among the plurality of second configuration parameters stored in the nonvolatile memory without performing the training operation, and drive the memory device according to the determined values of the third and the fourth configuration parameters.
