Method of transferring data between a memory comprising several banks and a data processing circuit, the method comprising the steps of: producing access requests (46, 47) defining each time a type of access and designating one or several memory locations (46a-d, 47a-b) arranged in accordance with a sequence suitable for said request, processing the requests in accordance with a successive sequence so as to transfer, for each processed request, data from the designated memory location to the data processing circuit, or vice versa, the processing of a request (46) designating memory locations (46a, 46b, 46c, 46d) associated with several banks (A, B, A, B) authorizing a transfer of data between the interface and the memory locations in a sequence which is different from the sequence associated with said request.
