A result message generated by the second DBMS is received wherein the result message comprises a result data portion, the result data portion including the routing information. The result message is modified to the first form wherein the result message comprises the internet message prefix, the internet message prefix comprising the client routing information obtained from the result data portion. In this manner, the result message may be routed to the client.

  • Publication number: 20080026528
    Abstract: Rows of memory cells are electrically isolated from one another by trenches formed in the substrate between the rows that are filled with a dielectric, commonly called “shallow trench isolation” or “STI.” Discontinuous source and drain regions of the cells are connected together by column oriented bit lines, preferably made of doped polysilicon, that extend in the column direction on top of the substrate. This structure is implemented in a flash memory array of cells having either one floating gate per cell or at least two floating gates per cell. A process of making a dual-floating gate memory cell array includes etching the word lines twice along their lengths, once to form openings through which source and drain implants are made and in which the conductive bit lines are formed, and second to form individual floating gates with a select transistor gate positioned between them that also serves to erase charge from the adjacent floating gates.

  • Publication number: 20070288695
    Abstract: An apparatus, system, and method are provided for sharing a cached security profile in a database environment. The apparatus, system, and method include a cache module for caching a security profile accessible to primary tasks and secondary tasks. An identification module is provided that distinguishes between primary tasks authorized to refresh the security profile and secondary tasks. A refresh module cooperates with the cache module and identification module to selectively refresh the security profile in response to a refresh request and expiration of the security profile such that an old version of the security profile is retained for use by secondary tasks until an execution window closes.

  • Publication number: 20070161191
    Abstract: An integrated non-volatile memory circuit is formed by first growing a thin dielectric layer on a semiconductor substrate surface, followed by depositing a layer of conductive material such as doped polysilicon on this dielectric layer, the conductive material then being separated into rows and columns of individual floating gates. Cell source and drain diffusions in the substrate are continuously elongated across the rows. Field dielectric deposited between the rows of floating gates provides electrical isolation between the rows. Shallow trenches may be included between rows without interrupting the conductivity of the diffusions along their lengths. A deep dielectric filled trench is formed in the substrate between the array and peripheral circuits as electrical isolation. Various techniques are included that increase the field coupling area between the floating gates and a control gate.

  • Publication number: 20070122980
    Abstract: Floating gate structures are disclosed which have a base field coupled with the substrate and a narrow projection extending from the base away from the substrate. In one form, surfaces of a relatively large projection provide an increased surface area for a control gate that wraps around it, thereby increasing the coupling between the two. In another form, an erase gate wraps around a relatively small projection in order to take advantage of sharp edges of the projection to promote tunneling of electrons from the floating to the erase gate. In each case, the control or floating gate is positioned within the area of the floating gate in one direction, thereby not requiring additional substrate area for such memory cells.

  • Publication number: 20070005678
    Abstract: A database server storing an authorization module and a rerouting module. The authorization module may be configured to define a second network interface module authorized to relay a response message queued in a hold queue associated with a first network interface module, where the response message is generated in response to a first request message. The rerouting module may be configured to route the response message from the hold queue to the second network interface module in response to a second request message requesting messages queued in the hold queue. The present invention thus enables delivery of requested queued messages despite failure of the request for such messages to correspond to the queue in which the messages are contained.

  • Publication number: 20060227620
    Abstract: Several embodiments of flash EEPROM split-channel cell arrays are described that position the channels of cell select transistors along sidewalls of trenches in the substrate, thereby reducing the cell area. Select transistor gates are formed as part of the word lines and extend downward into the trenches with capacitive coupling between the trench sidewall channel portion and the select gate. In one embodiment, trenches are formed between every other floating gate along a row, the two trench sidewalls providing the select transistor channels for adjacent cells, and a common source/drain diffusion is positioned at the bottom of the trench. A third gate provides either erase or steering capabilities. In another embodiment, trenches are formed between every floating gate along a row, a source/drain diffusion extending along the bottom of the trench and upwards along one side with the opposite side of the trench being the select transistor channel for a cell.

  • Publication number: 20060108647
    Abstract: Self-aligned trench filling is used to isolate devices in high-density integrated circuits. A deep, narrow trench isolation region is formed in a substrate between devices. The trench region includes two trench portions. A first trench portion, located above a second trench portion, is filled with a deposited dielectric. The second trench portion is filled with a grown dielectric. Filling the lower trench portion by growing a dielectric material provides for an even distribution of dielectric material within the lower portion. Filling the upper trench portion by depositing a dielectric material provides for an even distribution of material in the upper portion while also protecting against encroachment of the dielectric into device channel regions, for example. Devices can be fabricated by etching the substrate to form the trench region after or as part of etching one or more layers formed above the substrate for the device.

  • Publication number: 20060110880
    Abstract: Self-aligned trench filling to isolate active regions in high-density integrated circuits is provided. A deep, narrow trench is etched into a substrate between active regions. The trench is filled by growing a suitable dielectric such as silicon dioxide. The oxide grows from the substrate to fill the trench and into the substrate to provide an oxide of greater width and depth than the trench. Storage elements for a NAND type flash memory system, for example, can be fabricated by etching the substrate to form the trench after or as part of etching to form NAND string active areas. This can ensure alignment of the NAND string active areas between isolation trenches. Because the dielectric growth process is self-limiting, an open area resulting from the etching process can be maintained between the active areas. A subsequently formed inter-gate dielectric layer and control gate layer can fill the open area to provide sidewall coupling between control gates and floating gates.

  • Publication number: 20060069775
    Abstract: An apparatus, system, and method are provided for automatically freeing locked server resources using a timeout value closely related to actual real-time message delays plus a delta value that can be adjusted at a plurality of levels. The levels include default, server, connection, and transaction. The apparatus includes a timer, a communication module, a computation module, and a lock handler. The timer determines a timeout value for communications from a client to a server. The communication module sends an output message to the client and locks a server resource in anticipation of an acknowledgement (ACK) message from the client. The computation module, which calculates an ACK timer, includes a difference between a send time and a current time. If no ACK message has been received from the client and the ACK timer exceeds the timeout value, the lock handler may free the locked server resource.
