1. An apparatus, comprising:
a plurality of sense amplifiers;
a plurality of shared contacts, wherein individual ones of the plurality of shared contacts are coupled between at least two components of a sense amplifier of the plurality of sense amplifiers or between at least one component of a first sense amplifier of the plurality of sense amplifiers and at least one component of a second sense amplifier of the plurality of sense amplifiers, and wherein the individual ones of the plurality of shared contacts comprise a local line and a resistance; and
a global line coupled to the local line via the resistance of corresponding ones of the plurality of shared contacts, wherein the resistance at least partially isolates the local lines of the individual ones of the plurality of shared contacts from the global line causing each of the plurality of sense amplifiers to be at least partially isolated from one another.
