Abstract
An electronic chip includes at least a first array of first elementary cells and a second array of second elementary cells. The first and second elementary cells form two types of phase change memory having a storage element formed by a volume of phase change material having either a crystalline state or an amorphous state depending on the bit stored. Each first elementary cell includes a volume of a first phase change material, and each second elementary cell includes a volume of a second phase change material that is different from the first material. Each elementary cell includes a heating connector configured for the passage of a heating current adapted to cause a phase change of the volume of phase change material of the elementary cell.
