摘要： A reference current source for a magnetic memory device is preferably configured with magnetic tunnel junction cells and includes more than four reference magnetic memory cells to improve reliability of the magnetic memory device and to reduce sensitivity at a device level to individual cell failures. The reference current source includes a large number of magnetic memory cells coupled in an array, and a current source provides a reference current dependent on the array resistance. In another embodiment a large number of magnetic memory cells are coupled to current sources that are summed and scaled to produce a reference current source. A current comparator senses the unknown state of a magnetic memory cell. In a further embodiment, an array of magnetic memory cells is configured to provide a non-volatile, adjustable resistance. In a further embodiment, the array of magnetic memory cells is configured with a tap to provide a non-volatile, adjustable potentiometer.
