Abstract: A memory controller is used to control a first storage block having a first data rate and a second storage block having a second data rate. The memory controller includes; a memory interface that transceives a data signal and a data strobe signal with the first and second storage blocks, and a sub controller that stores access information about the first data rate and the second data rate. The sub controller may include a delay lookup table storing access information including first strobe adjustment timing information defining a first data strobe signal provided to the first storage block, and second strobe adjustment timing information defining a second data strobe signal provided to the second storage block.
