  • Patent number: 6978343
    Abstract: A content addressable memory (CAM) device having an error correction function. The CAM device includes an array of CAM cells, row parity storage elements and column parity storage elements. The row parity storage elements store row parity values that correspond to contents of respective rows of the CAM cells, and the column parity storage elements store column parity values that correspond to respective columns of the CAM cells. A bit error in the array is detected through row and column parity checking that uniquely identifies the row and column location of the error and enables correction of the error.

  • Patent number: 6973038
    Abstract: An apparatus and method are described for real-time buying and selling of bandwidth at differentiated quality of service levels, routing of excess traffic over the bandwidth purchased in real time, and billing and settlement of the transactions. In the present invention, a network user buys bandwidth to have a fixed capacity level. When the current traffic level exceeds the fixed capacity level, the network user buys additional capacity in real time as needed to handle the overflow. In addition, when the fixed capacity level exceeds the current traffic level, the network user can sell the excess capacity as available. Further, network users can select among a number of response times. The response times, which can be guaranteed, allow all traffic to be delivered within a time limit, or set time limits within which different types of data can be delivered.

  • Patent number: 6967855
    Abstract: A method and apparatus are described for the filtering of a common input string to generate various filtered comparand strings. The filtering of a common input string enables concurrent lookups in different tables to be performed on multiple filtered comparands by different CAM devices (or different blocks within a CAM device), to compare the data in the filtered comparand strings with data stored in its associative memory. By performing multiple lookups in parallel, rather than sequentially, packet throughput in a CAM may be significantly increased.

  • Patent number: 6954837
    Abstract: A memory system includes physical memory devices or ranks of memory devices that can be set to reduced power modes. In one embodiment, a hardware memory controller receives memory instructions in terms of a logical address space. In response to the relative usages of different addresses within the logical address space, the memory controller maps the logical address space to physical memory in a way that reduces the number of memory devices that are being used. Other memory devices are then set to reduced power modes. In another embodiment, an operating system maintains a free page list indicating portions of physical memory that are not currently allocated. The operating system periodically sorts this list by group, where each group corresponds to a set or rank of memory devices. The groups are sorted in order from those receiving the heaviest usage to those receiving the lightest usage.

  • Patent number: 6933610
    Abstract: In a semiconductor device having a semiconductor die without an ESD circuit and a separate ESD circuit and an external lead, the external lead is first bonded to the separate ESD circuit. Thereafter, the separate ESD circuit is bonded to the semiconductor die. As a result, in the process of bonding the semiconductor die, any ESD disturbance is absorbed by the ESD circuit. In addition, a semiconductor device such as a DDR DRAM memory device, has a chip carrier with a first surface having a plurality of leads and a second surface opposite to it with an aperture between them. A semiconductor die with a mounting surface and a bonding pad faces the second surface with the bonding pad in the aperture. An ESD circuit is mounted on the mounting surface in the aperture. A first electrical connector connects one of a plurality of leads to the ESD circuit and a second electrical connector connects the ESD circuit to the bonding pad.

  • Patent number: 6925467
    Abstract: A method for performing differencing and updating between electronic files is provided. A byte-level file differencing algorithm receives two byte streams corresponding to an original file and a new file. The new file includes updated and revised versions of the original file. The file differencing algorithm determines a longest common sub-string (LCS) between the two byte streams and divides each of the two byte streams into sub-streams. The sub-streams include the LCS along with prefix and suffix sub-streams to the LCS. The file differencing algorithm then recursively determines an LCS and divides each sub-stream until a size of the sub-streams is less than a pre-specified size. Byte-level differences are then identified between each of the corresponding sub-streams. Further, the file differencing algorithm defines a protocol for structuring a delta file by using a set of operation codes and a variable length integer format to eliminate redundant information in the delta file.
