    摘要: A method of establishing a reference level includes providing first and second non-overlapping paths from a first node to a second node, providing first and second reference magnetic random access memory (MRAM) elements in the first path, providing third and fourth reference MRAM elements in the second path, measuring a first value indicative of a resistance between the first node and the second node, and setting the reference level based at least in part on the measured value. Also an associated reference circuit.

    摘要: Embodiments disclosed include a memory array having a plurality of bit lines and a plurality of source lines disposed in columns. A plurality of word lines is disposed in rows. A plurality of storage elements have a first subset of storage elements electrically decoupled from the memory array and a second subset of storage elements coupled to the memory array. The memory array further includes a plurality of bit cells, each including one storage element from the second subset of storage elements coupled to at least two transistors. The bit cells are coupled to the plurality of bit lines and the plurality source lines. Each transistor is coupled to one word line. The memory array can further include logic to select a high performance mode and a high density mode.

    摘要: A two-transistor one-MTJ (2T1MTJ) three port structure includes two separate pin layer structures coupled to one free layer structure. The pin layer structures may include an anti-ferromagnetic layer (AFM) layer coupled to a pin layer. The free layer structure includes free layer coupled to a barrier layer and a cap layer. The free layer structure may include a thin barrier layer coupled to each of the pin layer stacks. The three port MTJ structure provides separate write and read paths which improve read sensing margin without increasing write voltage or current. The three port MTJ structure may be fabricated with a simple two step MTJ etch process.
