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. A selection circuit is provided that is capable of activating the first block of memory cells while deactivating the second block of memory cells. Further, a read circuit is provided that is capable of reading a logical state of a predetermined memory cell in the first block of memory cells with a reduced leak current by programming a first resistive state to the block selection elements corresponding to the first block of memory cells while programming a second resistive state to the block selection elements corresponding to the second block of memory cells.
