Driver with impedance control
An integrated circuit (IC) (100) may be configured to communicate signals to an external device ( e.g., a memory) (120) via a driver (140).The driver may include a plurality of driver circuits arranged in parallel with respect to each other.Each driver circuit in turn may include a plurality of driver sub-circuits.Based, for example, on the load presented by the external device (120) and/or operating conditions of the IC (100), a control circuit (180) may provide signals that enable individual ones of driver circuits to result in a selected driver strength.The control circuit (180) may also provide impedance control signals that enable or disable individual sub-circuits within one or more driver circuit, to thereby control the output impedance of each such driver circuit.		©Questel
