Abstract
This invention presents a novel write line segmentation architecture for writing magnetoresitive random access memories (MRAM). Only the memory cells in a selected segment get a high hard axis field generated by a write line current. Memory cells of deselected segments do not receive this hard axis field. This prevents an undesired state change in particularly sensitive memory cells.
