ABSTRACT:
A dynamically configured memory controller to prevent speculative memory accesses of non-well behaved memory. Such dynamic configuration of a memory controller may be accomplished by providing to the memory controller guard information associated with memory requests. The memory controller may then prevent speculative memory accesses when the guard information indicates that the memory requests are of non-well behaved memory. The guard information provided to the memory controller may include guard information associated with each memory request provided to the memory controller.
