Classification: CPC G | IPC G

Claim 9:
10. A memory system comprising:
a memory device; and
a memory controller that controls the memory device,
wherein the memory controller comprises:
a model manager configured to generate a regression model that predicts performance of the memory device based on log information on use of the memory device; and
a performance manager configured to determine a deterioration section, in which the performance of the memory device is deteriorated, based on the regression model and adjust a parameter value related to an operation of the memory device in the deterioration section,
wherein the log information includes information on a use time amount indicating an accumulated time amount for which power is applied to the memory device and a write amount indicating an amount of data on which a write operation is performed in the memory device during the use time amount, and
wherein the model manager:
obtains the log information for a predetermined period until the use time amount reaches a predetermined reference amount,
calculates increments of the write amount for the use time amount of each of obtained plural pieces of log information, and
generates the regression model based on an average value of the increments.
