Abstract: 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.

Abstract: Techniques for operating a switched-capacitor circuit to reduce input and feedback dependence and/or reduce reference modulation. A switched-capacitor circuit can be operated in four phases. In a first phase at a start of a cycle, the capacitor is charged/discharged by a common mode signal to mask any residual charge stored in the capacitor from a previous cycle. In a second phase, the capacitor is charged with an input signal. During a third phase, the capacitor is charged with a wide-bandwidth auxiliary reference signal, and during a fourth phase the capacitor is charged with a reference signal. During the third and fourth phases, the capacitor may be coupled to an integrating circuit to integrate a difference between the input signal and the reference signal.
