Disclosed herein are a current driving circuit and a light storage system having the same. The current driving circuit includes a plurality of channel circuits that include a first transistor into which the input current flows, a second transistor generating the output current by mirroring the input current, a plurality of switches connected between the first and second transistors in parallel and optionally electrically connecting the first and second transistors in response to the control signals, a controller optionally activating the control signals each corresponding to the switches according to the magnitude of the input current; and an adder that adds output currents of the channel circuits to generate driving current. The current driving circuit can stably supply the driving current while preventing a delay in the driving current.
