  • Method, system and apparatus for tri-stating unused data bytes during DDR DRAM writes
    Patent number: 8332876
    Abstract: A memory interface circuit includes a plurality of data bus drivers and logic adapted to be operatively responsive to write driver mask information. If desired, the plurality of bus drivers and the logic may be implemented in separate integrated circuits. The plurality of bus drivers are adapted to be responsive to a write operation. The logic is also adapted to disable any one of the plurality of data bus drivers based on the write driver mask information during the write operation.

  • AUTOMATED STORAGE AND DISPENSING SYSTEM
    Publication number: 20120234852
    Abstract: A storage and dispensing system including a cabinet having a frame with a plurality of separators, each separator including an opening formed therethrough. The system further includes a plurality of drawers, each drawer having a plurality of compartments configured to store an item therein. Each drawer is positioned adjacent to at least one of the separators and is movable relative to the adjacent separator such that each compartment of each drawer is positionable adjacent to the opening of the associated separator.

  • Self-refresh based power saving circuit and method
    Patent number: 7986580
    Abstract: A circuit includes a memory interface control circuit and a self-refresh adjustable impedance driver circuit having at least one adjustable impedance circuit. The memory interface control circuit selectively provides an impedance control signal based on memory self-refresh information. The self-refresh adjustable impedance driver circuit adjusts an impedance value of the adjustable impedance circuit in response to the impedance control signal. In addition, the self-refresh adjustable impedance driver circuit provides a memory interface signal based on the memory self-refresh information.
