Rambus Assigned Two Patents

Hybrid volatile and non-volatile memory device
with a shared interface circuit
Rambus, Inc., Sunnyvale, CA, has been assigned a patent (8,427,891) developed by Scott C. Best, Palo Alto, CA, for a "hybrid volatile and non-volatile memory device with a shared interface circuit."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A composite, hybrid memory device including a first storage die having an array of volatile storage cells and a second storage die having an array of non-volatile storage cells disposed within an integrated circuit package. The hybrid memory device includes a shared interface circuit to receive memory access commands directed to the first storage die and the second storage die and to convey read and write data between an external data path and the first and second storage dice."

The patent application was filed on April 17, 2008 (12/596,115).
 
Programmable memory repair scheme
Rambus, Inc., Sunnyvale, CA, has been assigned a patent (8,446,788) developed by Adrian E. Ong, Pleasanton, CA, and Fan Ho, San Ramon, CA, for a "programmable memory repair scheme."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "The present disclosure provides semiconductor devices and methods, systems, and apparatus for testing and operating the same. A semiconductor memory device includes storage elements and a repair circuit. The storage elements include primary storage elements and one or more redundant storage elements, the primary storage elements having respective addresses for memory access operations. The repair circuit is programmable by another semiconductor device separate from the memory device to recognize a malfunctioning address of the primary storage elements and the programmed repair circuit is configured to reroute memory access from a primary storage element having the recognized malfunctioning address to a corresponding redundant storage element."

The patent application was filed on April 9, 2009 (12/922,425).
