  • Patent number: 8174885
    Abstract: The present invention provides a novel read method of twin MONOS metal bit or diffusion bit structure for high-speed application. In a first embodiment of the present invention, the alternative control gates are set at the same voltage. In a second embodiment of the present invention, all the control gates are set at the operational voltage from the beginning. In both embodiments, the bit line and word gate are used to address the selected memory cell.

  • Patent number: 8139410
    Abstract: A nonvolatile trap charge storage cell selects a logic interconnect transistor uses in programmable logic applications, such as FPGA. The nonvolatile trap charge element is an insulator located under a control gate and above an oxide on the surface of a semiconductor substrate. The preferred embodiment is an integrated device comprising a word gate portion sandwiched between two nonvolatile trap charge storage portions, wherein the integrated device is connected between a high bias, a low bias and an output. The output is formed by a diffusion connecting to the channel directly under the word gate portion. The program state of the two storage portions determines whether the high bias or the low bias is coupled to a logic interconnect transistor connected to the output diffusion.
