MEMORY DEVICE, MEMORY SYSTEM INCLUDING THE SAME AND CONTROL METHOD THEREOF

摘要

PURPOSE: A memory device, a memory system including the same, and a controlling method thereof are provided to increase a data bandwidth by applying a row command and a column command to a memory device through an additional channel. CONSTITUTION: A row command decoder(403) generates an inner row command by decoding a row command applied through a first channel. A first bank selecting unit(407) transmits the inner row command to a bank corresponding to a first bank address. A second address storage unit(411) receives a column address and a second bank address corresponding to a column command through a second channel. A second bank selecting unit(413) transmits an inner column command to the bank corresponding to the second bank address.
