    摘要: Improved write operation techniques for use in phase-change-material (PCM) memory devices are disclosed. By way of one example, a method of performing a write operation in a phase-change-material memory cell, the memory cell having a set phase and a reset phase associated therewith, comprises the following steps. A word-line associated with the memory cell is monitored. Performance of a write operation to the memory cell for the set phase is initiated when the word-line is activated. The write operation to the memory cell for the set phase may then be continued when valid data for the set phase is available. A write operation to the memory cell for the reset phase may be performed when valid data for the reset phase is available. Other improved PCM write operation techniques are disclosed.

    摘要: A converter circuit and methods for operating the same. The converter circuit includes a supply voltage, a capacitor, an inductor, and four stacked switching elements. Each switching element is adjustable from a low resistance state to a high resistance state by a control signal. The inductor outputs current to a circuit load. The circuit may be operated in a first mode such that the output is adjustable between the supply voltage and half the supply voltage. Alternatively, in a second mode of operation, the output is adjustable from half the supply voltage to a ground voltage.
