A memory interface for use with a multiprocess memory system having a gating memory, the gating memory associating one or more memory access methods with each of a plurality of memory locations of the memory system wherein the gating memory returns a particular one access method for a particular one memory location responsive to a memory access instruction relating to the particular one memory location, the interface including: a request storage for storing a plurality of concurrent memory access instructions for one or more of the particular memory locations, each the memory access instruction issued from an associated independent thread context; an arbiter, coupled to the request storage, for selecting a particular one of the memory access instructions to apply to the gating memory; and a controller, coupled to the request storage and to the arbiter, for: storing the plurality of memory access instructions in the request storage; initiating application of the particular one memory access instruction selected by the arbiter to the gating memory; receiving the particular one access method associated with the particular one memory access method from the gating memory; and initiating a communication of the particular access method to the thread context associated with the particular one access instruction.
