The current control circuit receives a bias voltage, outputs a control signal at a second level during an enable duration of the reset pulse when the data is at a first level, and outputs a control signal at a first level during an enable duration of the set pulse when the data is at a second level. The current drive circuit outputs writing current to the phase-change memory array during the enable duration of the reset pulse or the set pulse. The writing driver circuit can select the reset pulse or the set pulse according to the logic level of the data, and control the level of current applied to the phase-change memory array according to the reset pulse or the set pulse.

    摘要: Disclosed is a phase-changeable memory device and a related method of reading data. The memory device is comprised of memory cells, a high voltage circuit, a precharging circuit, a bias circuit, and a sense amplifier. Each memory cell includes a phase-changeable material and a diode connected to a bitline. The high voltage circuit provides a high voltage from a power source. The precharging circuit raises the bitline up to the high voltage after charging the bitline up to the power source voltage. The bias circuit supplies a read current to the bitline by means of the high voltage. The sense amplifier compares a voltage of the bitline with a reference voltage by means of the high voltage, and reads data from the memory cell. The memory device is able to reduce the burden on the high voltage circuit during the precharging operation, thus assuring a sufficient sensing margin during the sensing operation.
