Abstract:
A method for operating a memory controller capable of controlling a maximum count of a read retry operation is disclosed. The method includes programming a first real time clock (RTC) value indicating a time-of-day when a program operation is performed when the program operation for programming a data to a storage region of a non-volatile memory, obtaining information for the storage region by using the first RTC value read from the non-volatile memory and a second RTC value indicating a time-of-day when a read operation is performed, when the read operation for the data programmed to the storage region is performed, and decreasing a maximum count of a read retry operation by using the information, when the read retry operation is performed for the storage region.
