Method for error recovery operation of memory device and memory system

A method for error recovery operation of a memory device and a memory system are provided. The method includes performing a training operation of the memory device when the memory system is powered on; booting the operating system to a normal mode by operating the memory device using a selected operating frequency among a plurality of operating frequencies based on a result of the training operation; detecting an error frequency among the plurality of operation frequencies in response to a change in the selected operation frequency of the memory device by the operating system, the error frequency being an operation frequency that causes at least one error in the memory device; and storing information on the detected error frequency in a first register, the first register being included in a memory controller associated with the memory device. 提供用于存储器装置的错误恢复操作的方法和存储器系统。所述方法包括：在存储器系统上电时执行存储器装置的训练操作；通过基于训练操作的结果使用多个操作频率中的选择的操作频率来操作存储器装置，将操作系统启动至正常模式；响应于操作系统对存储器装置的选择的操作频率的改变而检测所述多个操作频率之中的错误频率，错误频率是导致存储器装置中的至少一个错误的
