A device controls access to a data memory includes secured memory areas and receiving read or read/write-access commands. The device also includes a storing unit for storing a plurality of attributes, and a reading unit for, reading an attribute corresponding to a secured memory area at which an access command is aimed. The attributes are saved in a dedicated area of the data memory, and the device comprises a synchronous attribute search circuit arranged for intercepting the access command, when an access command is sent to the data memory, reading in the data memory the attribute corresponding to the secured memory area at which the intercepted access command is aimed, then applying the access command to the data memory.
