Abstract: A method and a corresponding decoder for decoding a Manchester encoded binary data signal includes receiving the Manchester encoded binary data signal having a first sequence of central bit transitions and a second sequence of initial bit transitions. A local clock signal is generated, and the central bit transitions of the Manchester encoded binary data signal are determined. Determination of the central bit transitions includes measuring the time interval elapsing between a pair adjacent central bit transitions, expressed as a number N of cycles of the local clock signal, and selecting each successive central bit transition based upon the time interval N measured between the pair of central bit transitions which immediately precede the successive central bit transition.

Abstract: A process manufactures an interpoly dielectric layer for non-volatile memory cells of a semiconductor device with an interpoly dielectric layer. The process begins with forming the tunnel oxide, and hence the amorphous or polycrystalline silicon layer, using conventional techniques. After the amorphous or polycrystalline silicon layer is surface cleansed and passivated, the surface of the polycrystalline layer is nitrided directly by using radical nitrogen. This is followed by the formation of the interpoly dielectric, either as an ONO layer or a single silicon layer, by means of the CVD technique. Masking to define the floating gate may be performed immediately before or after the direct nitridation step is carried out. The equivalent electrical thickness of the interpoly dielectric, obtained by combining the nitride oxide layer and by the following dielectric, does not exceed 130 Angstroms in either the ONO layer or the single silicon layer embodiment.

Abstract: A method for simultaneously programming a pre-established number of memory cells includes setting an initial number of memory cells to be simultaneously programmed equal to the pre-established number, and subdividing the initial number of memory cells to be programmed into subsets of memory cells. A program operation for simultaneously programming all the memory cells of each subset of memory cells is executed by forcing a current through all the memory cells of each subset of memory cells. The current has a program voltage associated therewith. The program voltage is compared to a threshold voltage during execution of the program operation. The method further includes stopping execution of the program operation if the threshold voltage is surpassed, reducing the initial number of memory cells to be simultaneously programmed, and restarting from the subdividing.
