Abstract: Methods and apparatus are provided for programming a phase-change memory cell (10). A bias voltage signal (V BL ) is applied to the cell. A measurement portion (m) of this bias voltage signal has a profile which varies with time. A measurement (T M ), which is dependent on a predetermined condition being satisfied, is then made. The predetermined condition is dependent on cell current during the measurement portion (m) of the bias voltage signal. A programming signal is generated in dependence on the measurement (T M ), and the programming signal is applied to program the cell (10).

Abstract: The invention relates to an electromechanical switch device (100, 200), comprising a first switch portion (111, 112, 211, 212), a second switch portion (121, 122, 220) and an actuator device (130, 230). The actuator device (130, 230) is configured to provide an actuation force, thereby actuating the first and second switch portion (111, 112, 121, 122, 211, 212, 220) relative to each other in order to change from a disconnected to a connected state. The actuator device (130, 230) is further configured to provide the actuation force with a modulation at least when the first and second switch portion (111, 112, 121, 122, 211, 212, 220) are in the connected state. The invention furthermore relates to a method of operating an electromechanical switch device (100, 200).
