Patent ID: 10956349

Abstract:
An apparatus includes a control circuit comprising (i) a first differential data strobe input/output circuit having a first set of driver and termination control inputs and (ii) a second differential data strobe input/output circuit having a second set of driver and termination control inputs. The first and the second sets of driver and termination control inputs are independently programmable. The first and the second differential data strobe input/output circuits operate in a first mode when the first differential data strobe input/output circuit is connected to a first memory device having a first data width and the second differential data strobe input/output circuit is connected to a second memory device having the first data width. The first and the second differential data strobe input/output circuits operate in a second mode when the first differential data strobe input/output circuit and the second differential data strobe input/output circuit are connected in parallel to a single memory device having a second data width.
