    Abstract: A one-transistor (1T), one-selector (1S), one magnetic tunnel junction (1MTJ), spin torque transfer (STT), spin Hall effect (SHE), magnetic random access memory (MRAM) may be configured to provide separate write current and read current paths. In such a configuration, the write current may pass through a SHE electrode disposed proximate the MTJ device. The direction of write current flow through the SHE electrode determines spin polarization of the write current, the magnetic field orientation of a free magnetic layer in the MTJ device, and consequently the resistance of the MTJ device. The write current can be at a level sufficient to cause the reliable storage of binary information in the MTJ device. The read current, at a lower level than the write current, passes through the MTJ.

    Abstract: Shared source line magnetic tunnel junction (MTJ) bit cells (300A) employing uniform MTJ connection patterns for reduced area are disclosed. In one aspect, a two (2) transistor, two (2) MTJ (2T2MTJ) bit cell includes a shared source line system having first and second source lines. A uniform MTJ connection pattern results in the first source line (SL1) disposed in an upper metal layer and electrically coupled to a free layer of a first MTJ (304), and the second source line (SL2) disposed in a lower metal layer and electrically coupled to a second access transistor (310). Middle segments are disposed in middle metal layers to reserve the middle metal layers for strap segments (368) of a strap cell (300B) that is used to electrically couple the first and second source lines. Electrically coupling the first and second source lines using the strap cell allows each MTJ to logically share a single source line.

    Abstract: Magnetic random access memory (MRAM) bit cells (200) employing source lines (204) and/or bit lines (206) disposed in multiple, stacked metal layers to reduce MRAM bit cell resistance are disclosed. Related methods and systems are also disclosed. In aspects disclosed herein, MRAM bit cells are provided in a memory array. The MRAM bit cells are fabricated in an integrated circuit (IC) (202) with source lines and/or bit lines formed by multiple, stacked metal layers disposed above a semiconductor layer (210) to reduce the resistance of the source lines. In this manner, if node size in the IC is scaled down, the resistance of the source lines and/or the bit lines can be maintained or reduced to avoid an increase in drive voltage that generates a write current for write operations for the MRAM bit cells.
