And a method for manufacturing a data memory having a readable and writable, the well structure by microtip

摘要

It can be read and written by using the read microtip or write at least one close to the point zone to be read or written on the surface of the substrate, in the case of erasing or writing, the invention changes the physical state of this zone In the case of reading, or so as to relates to a data storage memory data so as to determine the physical state of the zone, stored in the zone is defined by the physical state of the zone. Is subdivided into a set of (75) islands separate in the layer of sensitive material in the first capable of changing state under the action of writing microtip, each island (75), the surface of the substrate, the action of writing microtip surrounded by (80) wells formed by the material of the second less sensitive or not sensitive, but the material of the second, completely separated from each other island individual. Material of the well is the same as the material of the island, but the difference of impurities, distinguish them from each other. The organization of the wells and the island, can be accomplished by self-assembly step of the material which can be a mass naturally to the island, or by photolithography. [Selection Figure Figure 3
