Abstract: An operating method of a memory controller is provided. The operating method includes receiving a first read data and a second conversion information, the second conversion information including data obtained by converting a second read data based on a linear operation, and the first read data and the second read data including data read from same memory cells; converting the first read data based on the linear operation to generate a first conversion information; performing a logical operation on the first conversion information and the second conversion information to generate an operation information; performing an inverse operation of the linear operation on the operation information to generate a reliability information; and correcting an error of the first read data based on the first read data and the reliability information.

Abstract: A memory controller and an operation method thereof are provided. The operation method includes storing a plurality of random sequences, selecting at least one random sequence among the plurality of random sequences according to a data pattern of a data block, and performing conversion by at least one of randomizing the data block using the selected at least one random sequence and derandomizing the randomized data block using the selected at least one random sequence.
