  • Memory cell strings in a resistive cross point memory cell array
    Patent number: 6865108
    Abstract: A data storage device that includes a memory cell string. The memory cell string includes a first memory cell and a second memory cell. The device also includes a circuit coupled to a node between the first memory cell and a second memory cell. The circuit is configured to detect a voltage change at the node in response to a voltage being provided to the memory cell string and the first memory cell being written to a first state.

  • System and method for reading a memory cell
    Patent number: 6836422
    Abstract: A method of performing a read operation from a first memory cell in a memory cell string that includes a first memory cell coupled to a second memory cell. The method includes providing a voltage to a first end of the first memory cell string that is closest to the first memory cell, providing a ground source to a second end of the first memory cell string that is opposite the first end, and determining whether a voltage change occurred at a node between the first and second memory cells in response to writing the first memory cell to a first state.
