Assignee: SK HYNIX INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 12:
13. A method of operating a memory controller that controls a memory device, the method comprising:
obtaining log information on use of the memory device for a predetermined period;
calculating increments of an average erase number for a use time amount of each of obtained plural pieces of log information;
generating a regression model that predicts a lifespan of the memory device based on the log information;
determining a deterioration section, in which performance of the memory device is deteriorated, based on the regression model; and
adjusting a parameter value related to an operation of the memory device in the deterioration section,
wherein the log information includes the use time amount indicating an accumulated time amount for which power is applied to the memory device and the average erase number of memory blocks included in the memory device during the use time amount,
wherein the log information is obtained for the predetermined period until the use time amount reaches a predetermined reference amount, and
wherein the regression model is generated based on an average value of the increments.
