Abstract:
An embodiment method for programming a differential type phase-change memory device comprises, in a first time interval, programming a direct memory cell or the respective complementary one pertaining to a first programming driver by means of a current between SET and RESET; and, in the same first time interval, simultaneously programming a direct memory cell or the respective complementary one pertaining to a second programming driver by means of the same current between SET and RESET. The method further comprises, in a second time interval, programming the other direct memory cell or the respective complementary one pertaining to the first programming driver by means of the other current between SET and RESET; and, in the same second time interval, simultaneously programming the other direct memory cell or the respective complementary one pertaining to the second programming driver by means of the same other current between SET and RESET.
