Abstract
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.
