    Abstract: A memory has magnetic tunnel junction elements with different resistances in different logic states, for bit positions in memory words accessed by a word line signal coupling each bit cell in the addressed word between a bit line and source line for that bit position. The bit lines and source lines are longer and shorter at different word line locations, causing a resistance body effect. A clamping transistor couples the bit line to a sensing circuit when reading, applying a current through the bit cell and producing a read voltage compared by the sensing circuit to a reference such as a comparable voltage from a reference bit cell circuit having a similar structure. A drive control varies an input to the switching transistor as a function of the word line location, e.g., by word line address, to offset the different bit and source line resistances.
