The invention includes a method of forming a magnetoresistive device. The method includes the steps of: analyzing a user search query to determine a subject matter of the query; and selecting a sub-set of information from the plurality of information sources based upon the determined subject matter of the query. A second conductive line functioning as a write line and read line and extending in the X direction is connected to free layers of the MTJ elements. The locking member is movable between an insertion position to allow insertion of the pin block and a locking position to lock the pin block in the tool body. The protecting device has the form of a cylindrical pipe with at least one slot extending from one end of the pipe to the other.
