Intel Assigned Two Patents

SATA power optimization
through automatic deeper power state transition
Intel Corp., Santa Clara, CA, has been assigned a patent (8,464,084) developed by Amber D. Huffman, Banks, OR, and Eng Hun Ooi, Penang, Malaysia, for a "SATA power optimization through automatic deeper power state transition."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A host device and a storage device with a SATA (SATA) architecture to independently transition to a deeper low power state after first entering an initial low power state without first transitioning to the Active state. The transition from the Partial state to the Slumber state is direct and the transition may be enabled, but not negotiated through a handshaking process."

The patent application was filed on Nov. 1, 2011 (13/287,013).

Reversible low-energy storage in phase change memory
Intel Corp., Santa Clara, CA, has been assigned a patent (8,467,239) developed by Johannes A. Kalb, San Francisco, CA and Brett E. Klehn, Santa Clara, CA, for a "reversible low-energy storage in phase change memory."

The abstract of the patent published by the U.S. Patent and Trademark Office states: "A phase change memory (PCM) device utilizes low energy pulses to write data to PCM storage elements (cells). Methods, devices and systems are described that use low energy reset pulses to reset cells that have been previously set using a method that keeps a portion of the PCM cells in an amorphous phase. The reset is reversible by utilizing a low energy set pulse."

The patent application was filed on Dec. 2, 2010 (12/958,502).
