  • Publication number: 20180366472
    Abstract: A non-volatile memory (NVM) cell includes a semiconductor wire including a select gate portion and a control gate portion. The NVM cell includes a select transistor formed with the select gate portion and a control transistor formed with the control gate portion. The select transistor includes a gate dielectric layer disposed around the select gate portion and a select gate electrode disposed on the gate dielectric layer. The control transistor includes a stacked dielectric layer disposed around the control gate portion, a gate dielectric layer disposed on the stacked dielectric layer and a control gate electrode disposed on the gate dielectric layer. The stacked dielectric layer includes a first silicon oxide layer disposed on the control gate portion, a charge trapping layer disposed on the first silicon oxide, and a second silicon oxide layer disposed on the charge trapping layer.

  • Publication number: 20180122818
    Abstract: A memory device includes a semiconductor substrate having a cell region and a peripheral region surrounding the cell region and a pair of control gate stacks on the cell region. Each of the control gate stacks includes a storage layer and a control gate on the storage layer. The memory device includes at least one high-? metal gate stack disposed on the substrate. The high-? metal gate stack has a metal gate and a high-? dielectric film wrapping around the metal gate, and a top surface of the control gate is lower than a top surface of the metal gate.

  • Patent number: 7336259
    Abstract: An input device has a body and a battery that is retained in the body. A receiver is coupled to a computer via a cable, with the body removably engaging the receiver. The computer delivers power through the cable and the receiver to charge the battery, while the input device simultaneously transmits operational signals to the receiver for further transmission to the computer.
