Abstract: An apparatus may include a control device configured to determine an operational mode of the apparatus. The apparatus may also include at least one output circuit coupled to the control device. The at least one output circuit may be configured to generate a desired output driver impedance (ODI) during an active operational mode. The least one output circuit may further be configured to independently generate a desired on-die termination (ODT) impedance during an inactive operational mode. Memory systems, memory devices, electronic systems, and related methods of operation are also described.

Abstract: Apparatuses and methods for setting operational parameters of a memory based on location are disclosed. The operational parameters may include operational parameters for an input/output circuit. For example, operational parameters may be for output driver circuit impedance, equalization for input receiver circuits, termination impedance, as well as others. Location information is provided to a memory device and used for setting the operational parameter. A nominal operational parameter setting may be offset based on the location information, thereby tailoring the operational parameter of the memory device according to location in some examples. The location information may be memory slot address for location based on memory module location. The location information may be related to a location of a memory device within a sub-system. The location information may be provided to unused terminals of a memory device, for example, unused data terminals in some examples.

Abstract: An apparatus may include at least one output circuit configured to generate a desired output driver impedance (ODI) during a first operational mode. The least one output circuit may further be configured to independently generate a desired on-die termination (ODT) impedance during a second operational mode. Memory systems, memory devices, electronic systems, and related methods of operation are also described.
