Abstract
A magnetic random access memory (MRAM) includes an array of magnetic memory cells arranged on a cross-point grid. Spurious voltages that build up on the stray wiring capacitance of unselected bit and word select lines are limited and discharged by diodes. The control of such spurious voltages improves device operating margins and allows the construction of larger arrays.
