1. A memory access system for accessing items in a memory, comprising: a plurality of buffers, each buffer corresponding to a different logical partition of the memory; and a memory access controller, operably coupled to the plurality of buffers, that is configured to: determine whether an addressed item is contained in a buffer of the plurality of buffers, based on an identification of the logical partition corresponding to the addressed item, load a plurality of items, including the addressed item, from the memory and into the buffer, if the addressed item is not in the buffer, and load a next plurality of items from the memory and into a next buffer, if the next plurality of items is not in the next buffer, so that the plurality of items and next plurality of items are available for direct access from the corresponding buffer and next buffer.
