Sense line and sense amplifier configurations and circuits for coupling to magnetic memory elements. A sense line comprising a twisted pair of conductors provides coupling along its length to the memory elements. A pair of sense lines may be connected in series or parallel to provide sense signal output pulses of increased amplitude or provide redundancy in the sensing scheme. Further permutations and combinations of the twisted pair sense line provide sense signal output pulses of different amplitude to also provide, e.g., half select pulses. A sense amplifier system utilizes multiplexing techniques to simplify the sense scheme and reduce the amount of circuitry required between the sense lines and the buffer system.
