Memory device having a systematic arrangement of logical data locations and having plural data portals

摘要

A memory device that includes a digital storage unit having a data storage unit that stores data in a systematic arrangement, a systematic arrangement of plural data portals each provided for accessing the data locations; a generator that produces systematic, cyclical, relative movement between the data locations and the data portals; and a controller that selects at least one of the data portals in accordance with an input command and a calculation based on the relative movement. When one or more of the plural portals is selected, data can be input or output in a manner which is predictable, straight-forward, free of scheduling constraints, and very efficient, without contention between the separate portals.
