    Abstract: The present disclosure includes apparatuses and methods for sensing a resistive memory cell. A number of embodiments include performing a sensing operation on a memory cell to determine a current value associated with the memory cell, applying a programming signal to the memory cell, and determining a data state of the memory cell based on the current value associated with the memory cell before applying the programming signal and a current value associated with the memory cell after applying the programming signal.

    Abstract: Apparatus and methods of forming a memory cell are described. In one such method, a forming charge applied to a memory cell, such as a Resistive RAM (RRAM) memory cell, is monitored to determine the progress of the forming the cell. If the cell is consuming charge too slowly, a higher voltage can be applied. If the cell is consuming charge too quickly, a lower voltage can be applied. The charge may be monitored by charging a capacitor to a certain level, then monitoring the discharge rate of the capacitor though the cell. The monitoring may use comparators to measure the charge. The monitoring may also use an analog to digital converter to perform the monitoring.
