摘要: Magnetic memory having separate read and write paths is disclosed. The magnetic memory unit includes a ferromagnetic strip having a first end portion with a first magnetization orientation, an opposing second end portion with a second magnetization orientation, and a middle portion between the first end portion and the second end portion, the middle portion having a free magnetization orientation. The first magnetization orientation opposes the second magnetization orientation. A tunneling barrier separates a magnetic reference layer from the middle portion forming a magnetic tunnel junction. A bit line is electrically coupled to the second end portion. A source line is electrically coupled to the first end portion and a read line is electrically coupled to the magnetic tunnel junction.

摘要: A method and apparatus for writing data to a non-volatile memory cell, such as an STRAM memory cell or an RRAM memory cell. In some embodiments, a plurality of N non-volatile memory cells, where N is a greater than two, are connected to a common floating source line. A write circuit is adapted to program a selected memory cell of the plurality to a selected data state by passing a write current of selected magnitude through the selected memory cell and concurrently passing a portion of the write current in parallel through each of the remaining N−1 memory cells of the plurality via the common floating source line.
