Abstract
The present invention is directed to a nonvolatile memory device that includes a plurality of memory slices, each memory slice including one or more memory sectors and a read circuit for sensing the resistance state of a magnetic memory cell in the memory sectors. The read circuit includes first and second input nodes; a sense amplifier having first and second input terminals; a first target resistor and a balancing resistor connected in series between the first input node and the first input terminal; a multiplexer having a first input, a second input, and an output, with the first input being connected to the second input node and the output being connected to the second input terminal; a second target resistor and an offset resistor connected in series between the second input node and the second input; and first and second current sources connected to the first and second input terminals, respectively.
