Abstract: A method for regulating the duty cycle of an input clock signal includes producing a second clock signal using a first adjustable delay circuit for varying the duty cycle. The second clock signal is applied to first and second circuits for respectively increasing and decreasing the duty cycle of the second clock signal. The method further includes monitoring if the first circuitry increases the duty cycle or if the second circuitry reducing the duty cycle saturates first. The duty cycle introduced by the first adjustable delay circuit is modified until saturation of the first and second circuits occur at substantially the same time.

Abstract: A metal frame patterned by die stamping has the outermost end portion of each patterned pin extending freely, without constraints, from a line of metal bridge connections (dam bar). The end face of each pin is also covered, as well as other surfaces of the frame, by a coating layer or multilayer of metals different from the metal of the die stamped frame. The coating layer or multilayer contains at least on its outer surface, a noble metal such as palladium or gold. The tip of the pins are not subject to cutting and/or trimming after plating the die stamped frame. The pins are not even cut or trimmed during separation of the patterned frame from the surrounding metal at the end of the encapsulation process, when the pins are then eventually bent into shape.

Abstract: A reading device having an A/D converter of n+m bits receiving an input signal correlated to the threshold voltage of the memory cell, and supplying a binary output word of n+m bits. The A/D converter is of a double conversion stage type, wherein a first A/D conversion stage carries out a first analog/digital conversion of the input signal to supply at the output a first intermediate binary word of n bits, and the second A/D conversion stage can be activated selectively to carry out a second analog/digital conversion of a difference signal correlated to the difference between the input signal and the value of the first intermediate binary word. The second A/D conversion stage generates at the output a second intermediate binary word of m bits that is supplied along with the first intermediate binary word to an adder, which generates the binary output word of n+m bits.
