Abstract
A circuit, for managing operations for accessing a flash memory on the basis of requests received from a main CPU and from an auxiliary CPU, may be configured to: associate with the main CPU, a higher access priority to the flash memory than the access priority of the auxiliary CPU; command, in the absence of further requests for accessing the flash memory, the access to the flash memory for the main or auxiliary CPU which has initiated a first access request; verify, following a receipt of a second access request, the access priority associated with this second access request; suspend one of the first or the second access request having lower priority; and authorize the other of the first or the second access request having higher priority.
