A memory access system using a machine instruction architecture having separate machine instructions to instruct a start of the atomic memory access and an end of the atomic memory access, respectively, comprises an atomic memory access memory array for storing a start/end of the atomic memory access, object memory region indicative information of an access request and an identifier of a subject of the access request, a means for generating combinatory signals thereof, a means for detecting the fact that a memory access request with discrepant identifiers has been newly issued for the object memory region to which the atomic memory access is being effected at present and a means for starting a processing routine corresponding thereto.
