    Abstract: A memory device includes an array of resistive memory cells. Each resistive memory cell in the array includes a first resistive memory element, a second resistive memory element electrically coupled with the first resistive memory element at a common node between a first terminal of the first resistive memory element and a first terminal of the second resistive memory element, and a transistor comprising a gate electrically coupled with the common node.

    Abstract: A content addressable memory can include an array of memory cells having multiple memory elements, such as RRAM elements, to store data based on a plurality resistive states. A common switching device, such as a transistor, can electrically couple a plurality of the multiple memory elements with a matchline during read, write, erase, and search operations. In search operations, the memory cells can receive a search word and selectively discharge a voltage level on the matchline based on the data stored by the memory elements and the search word provided to the memory elements. The voltage level of the matchline can indicate whether the search word matched the data stored in the memory cells. The content addressable memory can potentially have an effective memory cell sizing under 0.5F2 depending on the number of layers of memory cells formed over the switching device.

    Abstract: A memory device may include a local bit line electrically coupled to a plurality of memory cells and a global bit line electrically coupled to the local bit line through first and second selectable parallel paths having first and second impedances, respectively. The first path may be active and the second path may be in an off state in at least one of a set operation or a forming operation. The second path may be active in a reset operation, wherein the second impedance of the second path has a lower impedance than the first impedance of the first path.

    Abstract: A memory device includes a local bit line coupled to a plurality of memory cells and a global bit line through first and second selectable parallel paths having first and second impedances, respectively. The first path is active in at least one of a set operation or a forming operation and the second path is active in a reset operation. A select device to select a memory element includes a drain having a first doping level and a source having a second doping level lower than the first doping level, wherein the device is configured to provide a first on impedance or a second on impedance to the resistive memory element in response to a control signal.
