Abstract: A voltage compensation circuit, a multi-level memory device with the same, and a voltage compensation method for reading the multi-level memory device are provided. When a memory cell is read, a reference voltage applied to the memory device is adjusted according to variation of characteristics of a drift resistance of a reference cell. The increased value of the reference voltage (i.e. a voltage difference) corresponds to a resistance variation caused by a drift condition. The drift compensation mechanism is adaptive to a compensation circuit of a read driver of the memory device, which can compensate variation of the voltage level when data is read from the memory cell. When the resistance drift occurs, a drift amount is calculated and is added to the reference voltage, in order to avoid the error in judgement caused by the resistance drift when the stored data is read out.

Abstract: A phase change memory (PCM) in which the phase change storage element is crystallized by a gradually increasing/decreasing operating current. The PCM comprises a switching circuit, the phase change storage element, a bit select switch, a pulse generating module, and a counting module. The switching circuit comprises a plurality of switches, selectively providing branch paths to an output terminal of a current source. The bit select switch controls the conduction between the phase change storage element and the output terminal of the current source. The pulse generating module outputs a pulse signal oscillating between high and low voltage levels. When enabled, the counting module counts the oscillations of the pulse signal, and outputs the count result by a set of digital data. The set of digital data are coupled to the switching circuit to control the switches therein.
