  • Phase-change memory cell, and method for manufacturing the phase-change memory cell
    Patent number: 9991316
    Abstract: A phase-change memory cell, comprising: a substrate housing a transistor, for selection of the memory cell, that includes a first conduction electrode; a first electrical-insulation layer on the selection transistor; a first conductive through via through the electrical-insulation layer electrically coupled to the first conduction electrode; a heater element including a first portion in electrical contact with the first conductive through via and a second portion that extends in electrical continuity with, and orthogonal to, the first portion; a first protection element extending on the first and second portions of the heater element; a second protection element extending in direct lateral contact with the first portion of the heater element and with the first protection element; and a phase-change region extending over the heater element in electrical and thermal contact therewith.
