Abstract: In a storage system (20) for an electronic device (27), a system controller (21) is connected to an embedded storage device (23) for supervising writing and reading operations in the embedded storage device; a data manager (36) based upon a microprocessor (38) is integrated in the embedded storage device (23) and provides a high-level abstraction of the physical organization of the embedded storage device (23) through the definition of an own logic map. The data manager (36) is implemented outside the controller (21). The controller (21) is formed in a first semiconductor material region, the embedded storage device (23) is formed in a second semiconductor material region distinct from the first semiconductor material region, and the data manager (36) is formed in a third semiconductor material region distinct from the first semiconductor material region.
