Abstract
An apparatus for providing a read signal at an output locus for access by an information processing device receives an input signal containing the information; the apparatus includes: (a) a read signal control unit receiving the input signal at a control unit input locus; the control unit is coupled with the output locus and controls the read signal; (b) a plurality of switches; and (c) a plurality of bias arrays coupled with the switches. A first bias array set cooperates with the plurality of switches in a first orientation to couple the first bias array set with the control unit to establish a first operational mode. A second bias array set cooperates with the plurality of switches in a second orientation to couple the second bias array set with the control unit to establish a second operational mode.
