摘要： An embodiment is proposed for trimming a programmable delay line in an integrated device, which delay line is adapted to delay an input signal being synchronous with a synchronization signal of the integrated device—by a total delay. An embodiment of a corresponding method includes the steps of: preliminary programming the delay line to provide a selected nominal value of the total delay equal to a period of the timing signal, and trimming the delay line to vary an actual value of the total delay until the actual value of the total delay matches the period of the synchronization signal.

摘要： A column decoder is for a phase-change memory device provided with an array of memory cells, a reading stage for reading data contained in the memory cells, and a programming stage for programming the data. The column decoder selects and enables biasing of a bitline of the array and generates a current path between the bitline and the reading stage or, alternatively, the programming stage, respectively during a reading or a programming operation of the contents of the memory cells. In the column decoder, a first decoder circuit generates a first current path between the bitline and the reading stage, and a second decoder circuit, distinct and separate from the first decoder circuit, generates a second current path, distinct from the first current path, between the bitline and the programming stage.

摘要： A non-volatile semiconductor memory device including an output connected to a row line and two supply terminals. Each elementary stage has an upper branch with a p-channel MOS transistor and a lower branch with an n-channel MOS transistor. In order to permit the memory to be erased line by line without having to use components capable of withstanding high voltages, each elementary stage has two supplementary MOS transistors, namely an n-channel transistor in the upper branch and a p-channel transistor in the lower branch. In this way it becomes possible to bias the elementary stages in such a manner the in the reading and programming phases the upper branch will function as pull-up and the lower branch as pull-down, while in the erasure phase the upper branch functions as pull-down and the lower branch as pull-up.
