Abstract
Disclosed are apparatus and methods for efficiently writing states to one or more magneto-resistive elements. In one embodiment, current switches are provided for directing a write current through a number of write lines to control the write state of the magneto-resistive elements. In another embodiment, a sense current is selectively controlled to control which magneto-resistive elements are written to a particular state. In both embodiments, a latching element may be used to sense the state of the magneto-resistive elements, and may assume a corresponding logic state.
