Methods and devices for reading and programming a state of a switch device are presented. The programming of the state of the switch device is performed by providing driving pulses to the switch device. The amplitude and the width of the driving pulses are a function of one or more of a) temperature of the switch device, b) desired state of the switch device, and c) operational time of the switch device. The described devices include a device to store the data demonstrating the functional relation between the amplitude and the width of the driving pulses and the temperature of the switch device. Such device can be a lookup table or an arithmetic logic unit (ALU). The disclosed switch devices can be PCM switches.
