Abstract: An apparatus for outputting an internal state of a memory apparatus and a memory system using the apparatus are provided. The apparatus includes a state signal generating circuit that generates a first signal indicating an internal operation state of the memory apparatus, and a state signal output control circuit that receives the first signal and outputs a second signal to an output pad based on a chip enable signal or an initially set function command, or both. The first signal indicates one state from among two states and the second signal indicates one state from among three states.
