  • Publication number: 20050180210
    Abstract: Non-volatile memory cells store a level of charge corresponding to the data being stored in a dielectric material storage element that is sandwiched between a control gate and the semiconductor substrate surface over channel regions of the memory cells. More than two memory states are provided by one of more than two levels of charge being stored in a common region of the dielectric material. More than one such common region may be included in each cell. In one form, two such regions are provided adjacent source and drain diffusions in a cell that also includes a select transistor positioned between them. In another form, NAND arrays of strings of memory cells store charge in regions of a dielectric layer sandwiched between word lines and the semiconductor substrate.

  • Publication number: 20050114454
    Abstract: A message is received in a first form for communicating with a first DBMS wherein the first form comprises an internet message prefix and a data portion, the internet message prefix comprising routing information for a client. The message is modified into a second form wherein the client routing information is integrated into the data portion of the message and wherein the second form of the message is utilized to communicate with a second DBMS. 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: 20050114604
    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.
