A memory device with a self-copy function includes a memory cell array having first and second banks, and a memory interface. The memory interface reads data from a memory area of the first bank corresponding to a source address contained in previously set self-copy information and writes the read data to a memory area of the second bank corresponding to a destination address contained in the self-copy information via a self-copy data path when a self-copy signal is activated by an external self-copy start request.
