That is a generalized summary of the patent, not the claimed scope of protection, which reads, for example, "a system for processing information, the system comprising: a memory configured to hold data; at least two processors, each configured to perform operations, and to generate an access request when one of the operations involves access to the data, wherein each access request includes an indication of whether or not this occurrence of the access request is to be performed in a sequential order among other occurrences of the access request and, if so, an indication of a specified order; and a controller configured to receive the access requests from each of the processors, to determine a performance order for the access requests, and to provide the access requests to the memory in the performance order, wherein the performance order conforms to the specified order when the access requests indicate the specified order."
