    Abstract: Dielectric regions (210) are formed on a semiconductor substrate between active areas of nonvolatile memory cells. The top portions of the dielectric region sidewalls are etched to recess the top portions laterally away from the active areas. Then a conductive layer is deposited to form the floating gates (410). The recessed portions of the dielectric sidewalls allow the floating gates to be wider at the top. The gate coupling ratio is increased as a result. Other features are also provided.

    Abstract: In a memory cell (110) having multiple floating gates (160), the select gate (140) is formed before the floating gates. In some embodiments, the memory cell also has control gates (170) formed after the select gate. Substrate isolation regions (220) are formed in a semiconductor substrate (120). The substrate isolation regions protrude above the substrate. Then select gate lines (140) are formed. Then a floating gate layer (160) is deposited. The floating gate layer is etched until the substrate isolation regions are exposed. A dielectric (164) is formed over the floating gate layer, and a control gate layer (170) is deposited. The control gate layer protrudes upward over each select gate line. These the control gates and the floating gates are defined independently of photolithographic alignment. In another aspect, a nonvolatile memory cell has at least two conductive floating gates (160). A dielectric layer (164) overlying the floating gate has a continuous feature that overlies the floating gate and also overlays a sidewall of the select gate (140). Each control gate (160) overlies the continuous feature of the dielectric layer and also overlies the floating gate. In another aspect, substrate isolation regions (220) are formed in a semiconductor substrate. Select gate lines cross over the substrate isolation regions. Each select gate line has a planar top surface, but its bottom surface goes up and down over the substrate isolation regions. Other features are also provided.

    Abstract: In a nonvolatile memory cell, the floating gate (160) has an upward protruding portion. This portion can be formed as a spacer over a sidewall of the select gate (140). The spacer can be formed from a layer (160.2) deposited after the layer (160.1) which provides a lower portion of the floating gate. Alternatively, the upward protruding portion and the lower portion can be formed from the same layers or sub-layers all of which are present in both portions. The control gate (170) can be defined without photolithography. Other embodiments are also provided.

    Abstract: A system and method for charging a battery is provided. The method includes applying an excitation current pulse to the battery to determine the battery type and whether the battery is capable of holding a charge. To charge the battery, a series of current pulses are applied in groups with the average current being reduced for each succeeding group to take advantage of changing battery charge acceptance. When the voltage of the battery matches a predetermined value, application of the current pulse groups is ended. A single current pulse is then applied to complete the battery charge.

    Abstract: Detectors and methods for rapid charging each provide efficient recharging of batteries of various types and ratings. During the charging process, the detector preferably monitors battery state of charge (SOC) and/or battery charge acceptance (BCA) in order to select appropriate waveforms for the charging signal. The charging signal may be a pulse width and amplitude modulated current, voltage or power waveform with the amplitude and pulse width of each charging pulse being selected based upon the detected battery SOC and/or BCA.
