    摘要: The invention relates to an integrated semiconductor memory (1) comprising a storage medium (6) that is located between two electrodes (10, 20) and that takes the form, for example, of a phase change medium. The storage medium (6) can adopt a first state or a second state by means of an electric current and can thus store information. According to the invention, the memory is provided with a layer plane (L) in which foreign particles of a material (4) are embedded, causing a local increase in the current density in the storage medium and a reduction of the programming current that is required to perform the reprogramming procedure. The current consumption of storage cells containing a phase-change medium thus decreases, so that for the first time such cells can be configured with minimum dimensions, together with other components such as transistors, and integrated into a single semiconductor circuit, instead of having to be provided in separate sub-circuits.
