Abstract
An embodiment phase-change memory device includes a memory array provided with a plurality of phase-change memory cells, each having a body made of phase-change material and a first state, in which the phase-change material is completely in an amorphous phase, and at least one second state, in which the phase-change material is partially in the amorphous phase and partially in a crystalline phase. A programming-pulse generator applies to the memory cells rectangular dynamic-programming pulses having an amplitude and a duration calibrated for switching the memory cells from the first state to the second state.
