In some examples, memory devices at or on the DIMM may be accessed via one or more data channels. The one or more data channels arranged such that the DIMM is configured to operate in a dual channel mode that includes two data channels or to operate in a single channel mode that includes a single data channel.
Abstract:
An output driver includes control logic configured to switch on a pull-up circuit and a pull-down circuit to provide an output impedance for a logic low on a transmission line. The output driver includes a variable pull-up resistor. The control logic is configured to switch on the pull-up circuit to a first value of impedance to drive a logic high on the transmission line. The control logic is configured to switch on the pull-up circuit to a second value of impedance and to switch on the pull-down circuit to provide the output impedance to drive a logic low on the transmission line. The system could alternatively be configured for the inverse to switch on a combination of pull-up and pull-down circuits for a logic high, where the pull-down circuit is switched on for a logic low.
