Small and Power-Efficient Cache That Can Provide Data for Background DMA Devices While the Processor Is in a Low-Power State

Sun Microsystems Inc.

A patent family: one line of work, grouped by real continuity rather than by a technology label inferred from titles. 5 of these applications claim priority to application 60/736,632, filed Nov 15, 2005. A shared origin can cover several different claimed inventions, which is why members here may not share a title. In-force patents first, soonest term end first, then patent number. Expired patents follow, in the same order.
