ABSTRACT:
An apparatus configured according to characteristics for driving a write head to write to a memory device includes: (a) a current directing circuit directing a write current through a first circuit path or a second including the write head in response to a first or second write signal; (b) at least one of: (1) an impedance system for including at least one impedance unit within each of the first and second current paths; and (2) a current system for including at least one circuit element between a locus at each end of said write head and a supply voltage; and (c) a control unit coupled with at least one of the impedance system and the current system for effecting the including for at least one of the impedance system and the current system to effect configuring the apparatus.
