A device for detecting at least one substance of a fluid includes at least one piezo-acoustic resonator with at least one piezo layer, an electrode arranged on the piezo-electric layer, at least one other electrode arranged on the piezo-electric layer and a surface section used for sorption of the substance of the fluid. The piezo-electric layer, the electrodes and the surface section are disposed in such a way that electric control of the electrodes leads to an oscillation of the resonator at a resonance frequency which depends upon the amount of the substance which is sorbed on the surface section. The thickness of the pioelectric layer is in the region of 0.5 to 20 μm and the resonance frequency of the oscillation ranges from 500 MHz to 2 GHz. The device is a mass sensor with a piezo-acoustic high-frequency thin film resonator.

An improved NAND Flash memory and word line selection method has been described, that takes advantage of the asymmetric nature of the word line to word line capacitive coupling to reduce word line selection delay by driving the adjacent word lines to a higher initial voltage and then reducing it to the final target voltage. As the capacitive coupling in between the NAND word lines is a larger effect when the voltages are being lowered, this has the effect of damping out the voltage initially induced in the lower voltage word line by the rising voltages on the adjacent word lines, reducing the overall selection time.

An array structure of single-level poly NMOS EEPROM memory cells and method of operating the array is discussed implemented in a higher density embedded EEPROM layout that eliminates the use of high voltage transistors from the array core region. If they are utilized, the high voltage transistors are moved to row and column drivers in the periphery region to increase array density with little or no added process complexity to allow economic implementation of larger embedded SLP EEPROM arrays. During program or erase operations of the array, the method provides a programming voltage for the selected memory cells of the array, and a half-write (e.g., mid-level) voltage to the remaining unselected memory cells to avoid disturbing the unselected memory cells of the array.

Methods and apparatus utilizing a stepped floating gate structure to facilitate reduced spacing between adjacent cells without significantly impacting parasitic capacitance. The stepped structure results in a reduced surface area of a first floating gate in close proximity to an adjacent floating gate with substantially no reduction in coupling area, thus facilitating a reduction in parasitic capacitance leading to improved gate coupling characteristics. Also, because of the reduced surface area exposed to adjacent floating gates, the floating gates may be formed with reduced spacing, thus further leading to improved gate coupling characteristics.
