    摘要: A non-volatile memory cell with a programmable unipolar switching element, and a method of programming the memory element are disclosed. In some embodiments, the memory cell comprises a programmable bipolar resistive sense memory element connected in series with a programmable unipolar resistive sense switching element. The memory element is programmed to a selected resistance state by application of a selected write current in a selected direction through the cell, wherein a first resistance level is programmed by passage of a write current in a first direction and wherein a second resistance level is programmed by passage of a write current in an opposing second direction. The switching element is programmed to a selected resistance level to facilitate access to the selected resistance state of the memory element.

    摘要: A method and apparatus for reading data from a non-volatile memory cell. In some embodiments, a cross-point array of non-volatile memory cells is arranged into rows and columns that are each controlled by a line driver. A read circuit is provided that is capable of reading a logical state of a predetermined memory cell by differentiating a non-integrated first reference value from a non-integrated second reference value. Further, each reference value is measured immediately after configuring the column corresponding to the predetermined memory cell to produce a first and second amount of current.
