Abstract: Systems and method are directed to Universal Flash Storage (UFS) memory system configured to support deep power-down modes wherein the UFS memory system is not required to be responsive to commands received from a host device coupled to the UFS memory system. Correspondingly, in the deep power-down modes, a link or interface between the UFS memory system and the host device may also be powered down. The UFS memory system may enter the deep power-down modes based on a command received from the host device or a hardware reset assertion, and exit the deep power-down modes based on a hardware reset de-assertion or power cycling. While in deep power-down modes, the power consumption of the UFS memory device is substantially lower than the power consumption of the UFS memory device in conventional power modes.

Abstract: In conventional systems with a plurality of UFS devices daisy-chained to a UFS host, a UFS device driver must be able to differentiate among the links, and send either link control messages or data/management (D/M) messages to a UFS host controller. This can make force the UFS device driver to be complicated and error prone. To address this issue, a host controller can provide a uniform view of a plurality of daisy-chained devices to a device driver of a host. For example, the host controller can be such that from the perspective of the device driver, each device can appear to be a point-to-point connected device. This can allow the device driver to use a same set of link control messages to control the links. In this way, the device driver can be simplified and thus less error prone.

Abstract: Systems and method are directed to a Universal Flash Storage (UFS) host capable of interfacing one or more UFS devices. The UFS host includes a plurality of mobile-physical-layers (M-PHYs) for supporting one or more lanes of traffic between the UFS host and the one or more UFS devices. A Reference M-PHY MODULE Interface (RMMI) router is coupled between a Unified Protocol link layer (Unipro) and the plurality of M-PHYs. The RMMI router is configurable in a transparent mode to pass traffic, without routing, between the UFS host and a 2-lane embedded UFS device through the two M-PHYs. The RMMI router is configurable in a routing mode, to route traffic to a first M-PHY interfacing a 1-lane embedded UFS device or to a second M-PHY interfacing a 1-lane removable UFS card. The RMMI router is configurable based on metal strap or read only memory (ROM) setting.

Abstract: Systems and method for a host-driven data refresh of a Flash memory include registers provided in the Flash memory for storing various settings related to refresh operations, such as, when to start/stop refreshing, target partitions in the memory, target start/end address ranges for refreshing, refresh algorithms, refresh rate requirements, etc. A host can control the various settings for start/stop refreshing, target partitions in the memory, target start/end address ranges for refreshing, refresh algorithms, through the corresponding registers; and the Flash memory can control various values related to refresh rate requirements through corresponding registers. In this manner, a standard platform or interface is provided within the Flash memory for refresh operations thereof.

Abstract: A method of tuning a database query includes selecting a database query, parsing the selected database query to determine relationships between portions of the selected database query, selecting an optimization mode from a plurality of available optimization modes, tuning the selected database query by modifying, at least one portion of the selected database query based on the determined relationships and the selected optimization mode and displaying the modified database query.

Abstract: A peripheral and a method for securing and operating the peripheral. A preferred embodiment comprises scanning a communications media for identifiers of devices utilizing the communications media, selecting identifiers from the scanned identifiers, applying a logical combination function to the selected identifiers, and securing the peripheral based on an output of the applying. The securing of the peripheral can be totally transparent to a device coupled to the peripheral, as is the granting of access to the peripheral. No changes to the device or to software in the device are needed, which can simplify development and implementation of the present invention. Furthermore, without requiring changes to the devices to which the peripherals are attached, the cost of the implementation can be kept to a minimum, while not affecting the reliability of the devices.

Abstract: A technique of processing an image data for output on a digital image device that compresses (164) a portion of a received image data to a data frame (110) according to a predefined size that is optimized for output with a processor of the device. The portion of the image data that is defined by the data frame is outputted (166, 186) to another source, and for any empty bits in the data frame, a zero bit is inserted (174).

Abstract: A method and apparatus for viewing the effect of changes to an index for a database table on an optimization plan for a database query, such as an SQL statement. A virtual table is created which mimics the structure of an original table on the database. The virtual table is created by copying the original table, excluding any data in the original table. Any existing original indexes associated with original table are copied to define a virtual index associated with the virtual table. References in the query to the original table are replaced with references to the virtual table. The database management system then determines a new optimization plan for the query.

Abstract: A multi-configuration portable electronic device is provided. The device includes at least one processor, a first body element including at least one input, and a second body element including a display. The second body element is pivotally coupled to the first body element such that the device can be positioned into a plurality of physical configurations. In response to a change in the physical configuration of the device, there is a change in at least two of a mode of operation of the input device, a mode of operation of the display, and an active software application being executed by the processor. In a preferred embodiment, the physical configurations of the device include a portrait configuration in which the device functions as a wireless phone, and a landscape configuration in which the device functions as a text messaging pager, PDA, handheld computer, electronic organizer, or media player.

Abstract: A bi-directional voltage translator (125) has a first port (201) that communicates a signal at a first voltage level, and second port (202) that communicates a signal at a second voltage level different from the first voltage level. A switching circuit, including a bipolar junction transistor (210) and a switch (220), couples both ports (201, 202). The transistor (210) has a collector (211) coupled, via a pull-up circuit (206), to a voltage source corresponding to the first voltage level, and to the first port (201), and an emitter (212) coupled to the second port. The base (213) of the transistor (210) is coupled, via a pull-up circuit (207), to a voltage source corresponding to the second voltage level. Preferably, the switch (220) is Schottky diode or other diode having a forward voltage drop.
