<p>The invention relates to data storage memories, that can be written and read by using at least one write or read microtip which comes near to a point zone to be written or to be read on the surface of a substrate, either in order to change the physical state of this zone, when writing or erasing, or in order to determine the physical state of the zone, when reading, the data stored in the zone being defined by the physical state of the zone. The surface of the substrate is subdivided into a set of individual islands (75) of a layer of a first sensitive material capable of changing state under the action of the write microtip, each island (75) being surrounded by a well (80) formed by a second material which is not or not very sensitive to the action of the write microtip, this second material completely separating the individual islands from one another. The material of the wells is the same as that of the islands, but differentiation impurities distinguish them from one another. The organization into islands and into wells may be obtained by photolithography or by a step of self-organization of materials capable of agglomerating spontaneously into islands.</p> |
