A method for preparing error recovery of a memory device included in a memory system includes performing a training operation of the memory device upon power-on of the memory system, booting an operating system into a normal mode by operating the memory device using a selected operation frequency of a plurality of operation frequencies based on results of the training operation, detecting an error frequency among the plurality of operation frequencies in response to a change of the selected operation frequency of the memory device by the operating system, the error frequency being an operation frequency which causes at least one error in the memory device, and storing information regarding the detected error frequency in a first register included in a memory controller associated with the memory device.

Memory system including memory controller and memory device and method for recovering from an error thereof

Disclosed is an electronic device including a memory module that includes at least one dynamic random access memory, and a processor configured to access the memory module, determine a corrected error count associated with an address of a corrected error in response to the corrected error being detected when data are read from the memory module, read an error log associated with the corrected error, determine a risk level of the corrected error based on the error log, and schedule a post package repair (PPR) for the address of the corrected error in response to the risk level of the corrected error being high.
