Systems and methods for performing low voltage charging of a high voltage, series-connected string of battery modules are disclosed. A battery pack system may include a plurality of battery cells, including one or more groups of battery cells coupled in parallel. A processor may be configured to select a sub-group of battery cells from a group of battery cells for charging separately from other battery cells of the selected group of battery cells. The group of battery cells may be reconfigured to allow charging of the sub-group of battery cells separate from the other battery cells. The sub-group of battery cells may be charged, and then the group of battery cells may be reconfigured to allow operation of the sub-group of battery cells with the other battery cells. During charging, the sub-group of battery cells may be unavailable but other battery cells may continue to discharge.

A memory device is coupled to a subset of lines of a data input/output (I/O) bus. The memory device includes an on-die active termination circuit for terminating the subset of lines of the data I/O bus with a selected impedance being one of a plurality of selectable impedances; a termination value register being coupled to the on-die active termination circuit for storing a value representing the selected impedance; and a termination value setting circuit being coupled to the termination value register, for setting the value representing the selected impedance in the termination value register.
