Memory controller and method of operating the same

Abstract

Provided herein may be a memory controller and a method of operating the memory controller. The memory controller may control a memory device that stores data, and may include a bit counter configured to generate a count value by counting any one of bits in a programmed state and an erased state contained in the data, a flash translation layer configured to generate page information indicating an address of the data stored in the memory device, an additional data generator configured to generate judgment data for determining whether the data has changed, based on the count value and the page information, a comparator configured to generate comparison information by comparing the judgment data with detection data generated based on data read from the memory device, and a read data controller configured to perform an operation of correcting an error in the read data based on the comparison information.
