Abstract
A method for programming a phase-change-memory device of a differential type comprises, in a first programming mode, supplying, during a first time interval, a same first programming current, of a type chosen between a SET current and a RESET current, to all the direct and complementary memory cells that are to be programmed with said first programming current; and, in a second programming mode, supplying, during a second time interval, a same second programming current, of the other type chosen between a SET current and a RESET current, to all the direct and complementary memory cells that are to be programmed with said second programming current, thus completing, in just two time steps, writing of a logic word in the memory device.
