Resistive type memory device and integrated circuit including the same

The resistive memory device comprises a memory cell array and a control logic circuit. Wherein the control logic circuit controls access to the memory cell array in response to the command and address from the outside. The memory cell array includes a resistive memory cell of the second group having the resistive memory cells and the first feature size and a different second feature size of the first group having a first feature size (feature size) at least.
