The term "motor controller" or "motor driver" refers to a circuit that it's designed to drive motors.
Such a circuit is the L293D from ST which is a dual H-Bridge circuit. This means that it can drive two DC motors at the same time and allows the switching of the direction the motor turns, by logical inputs. It has a separate power supply for the motors, and it can be used with PWM in order to control the speed.
