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.

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.

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.

Abstract: The disclosure relates to a system and method of mapping a layout of a keyboard onto a keypad in an electronic device. The method comprises: providing a map of a keyboard layout as a collection of segments including a left column of segments and a right column of segments onto the keypad; providing a navigation system having programmable keys in the keypad for moving through the keyboard layout; and associating a set of characters in one segment of the segments to the programmable keys based on a signal received from the navigation system and a current mapping of the collection of segments to the programmable keys. The navigation system has: a left set of directional keys providing navigation controls for the programmable keys when the set of characters are from the left column of segments; and a right set of directional keys providing navigation controls for the programmable keys when the set of characters are from the right column of segments.
