Abstract
A memory controller for use in a computer system. The controller has a buffer having an input configured to receive read and write requests. Each request has an associated memory address. For a selected received request, prior received requests out of a set of the received requests are determined. For each determined prior received request, that request's memory address is compared to the selected request's memory address to see if they match. If a match exists, the selected request is prevented from being memory executed.
