    Abstract: Some embodiments include apparatuses having a resistive memory device and methods to apply a combination of voltage stepping current stepping and pulse width stepping during an operation of changing a resistance of a memory cell of the resistive memory device. The apparatuses also include a write termination circuit to limit drive current provided to a memory cell of the resistive memory device during a particular time of an operation performed on the memory cell. The apparatuses further include a programmable variable resistor and resistor control circuit that operate during sensing operation of the memory device.

    Abstract: An apparatus is described that includes a bit line. The apparatus also includes first and second storage cells coupled to the bit line. The first storage cell has a first access transistor. The first access transistor is coupled to a first line resistance. The second storage cell has a second access transistor. The second access transistor is coupled to a second line resistance. The second line resistance is greater than the first line resistance. The apparatus also includes first and second drivers that are coupled to the bit line. The second driver is a stronger driver than the first driver. The apparatus also includes circuitry to select the first driver to write information into the first storage cell and select the second driver to write information into the second storage cell.
