  • Publication number: 20060068551
    Abstract: A method for embedding non-volatile memories with logic circuitry, without changing performance of both the logic circuitry and the NVM elements (and/or without changing a sequence of manufacturing steps for both the logic circuitry and the NVM elements). The embedding process includes insertion of NVM device and array process steps into an existing logic CMOS process in a way that maintains the CMOS performance, thereby enabling use of existing circuit libraries. The NVM may thus be combined with the high-speed low-voltage CMOS without any performance or reliability penalty.

  • Publication number: 20060056240
    Abstract: The present invention is a method circuit and system for erasing one or more non-volatile memory (“NVM”) cells in an NVM array. One or more NVM cells of a memory array may be erased using an erase pulse produced by a controller and/or erase pulse source adapted to induce and/or invoke a substantially stable channel current in the one or more NVM cells during an erasure procedure.

  • Patent number: 6829172
    Abstract: A method for programming an NROM cell which includes the steps of applying a drain, a source and a gate voltage to the cell and verifying a programmed or a non-programmed state of the cell. If the cell is in the non-programmed state, the method includes the steps of increasing the drain voltage and maintaining the gate voltage at a constant level during at least a part of the step of increasing. The steps of applying, verifying, increasing and maintaining are repeated until the cell reaches the programmed state.

  • Patent number: 6627555
    Abstract: A protection device which is active during the manufacturing process of a semiconductor chip includes a protection transistor and an antenna. The protection transistor is connected between a metal line having devices to be protected electrically connected thereto and a ground supply, where the metal line is connected to devices to be protected. The antenna is formed of the same metal layer as the metal line and controls the operation of the protection transistor during the manufacturing process. The antenna is connected to a gate of the protection transistor. Optically, there is a metal ring around the antenna which is connected to a drain of the protection transistor via the same metal layer as the metal line. During normal operation of the chip, the protection transistor is either active for other purposes or is turned off.
