Patent ID: 7872905

Claim:
A two-dimensional planar nonvolatile memory array system, comprising: a plurality of memory elements wherein each memory element stores at least one bit of data and formed between a top lead and a bottom lead, through which current is applied and travels, each memory element including, a magnetic fixed layer formed between the top and bottom leads; a magnetic free layer formed between the top and bottom leads; and a non-magnetic spacer formed between the fixed and free layers; and a memory controller operably coupled to the memory elements adapted to write data to the memory elements, wherein the memory controller is adapted to perform one or more of the following: write to one or more of the memory elements by applying signals to the one or more memory elements to be written to having frequencies that are less than the resonant frequencies of the memory elements to be written to; or inhibit writing to one or more of the memory elements by applying signals to the one or more memory elements not to be written to having frequencies that are more than the resonant frequencies of the memory elements not to be written to.
