Abstract:
A memory system includes a non-volatile memory and a controller. The controller is configured to maintain a relationship between a first parameter value and a second parameter value for each of some pages of the non-volatile memory, determine a first parameter value to be used for reading data from a target page of the non-volatile memory based on a first parameter value of a first page and a first parameter value of a second page, when the relationship is maintained for each of the first and second pages and is not maintained for the target page, and carry out a read operation with respect to the target page using the determined first parameter value.
