  • Patent number: 7362131
    Abstract: An integrated circuit device includes a programmable logic block, a monitoring input, a condition-sensing circuit coupled to the monitoring input and configured to generate a condition-sensed signal at an output in response to sensing a condition at the monitoring input, a first digital input, a first digital output, and a gating circuit configured in the programmable logic block and coupled between the first digital input and the first digital output. The gating circuit has a gating input coupled to the condition-sensing circuit and generates an output. The output is related to an input state of the first digital input in the absence of the condition-sensed signal and assumes an override state in the presence of the condition-sensed signal.

  • Patent number: 7360195
    Abstract: An FPGA architecture has top, middle and low levels. The top level of the architecture is an array of the B16×16 tiles arranged in a rectangular array and enclosed by I/O blocks on the periphery. On each of the four sides of a B16×16 tile, and also associated with each of the I/O blocks is a freeway routing channel. A B16×16 tile in the middle level of hierarchy is a sixteen by sixteen array of B1 blocks. The routing resources in the middle level of hierarchy are expressway routing channels M1, M2, and M3 including groups of interconnect conductors. At the lowest level of the semi-hierarchical FPGA architecture, there are block connect (BC) routing channels, local mesh (LM) routing channels, and direct connect (DC) interconnect conductors. Each BC routing channel is coupled to an expressway tab to provide access for each B1 block to the expressway routing channels M1, M2, and M3, respectively.

  • Patent number: 7360244
    Abstract: A firewall for authenticating a user access request is disclosed. The firewall device may include a proxy process for processing incoming connection requests. The proxy is configured to receive an access request from a user over a first communication medium and prompt the user for a username and a first password portion over the first communication medium. The firewall may then send a second password portion to the user over a communication medium other than said first communication medium responsive to receiving a valid user name and first password portion pair from the user. The firewall may then verify the access request responsive to receiving the second password portion from the user through the first communication medium. The firewall may send passwords to a mobile device for verification.

  • Patent number: 7342832
    Abstract: A flash memory array includes a reference bit line on which a reference current is imposed. During read operation, bit lines selected for reading are connected to current-to-voltage converters, each of which generates an output voltage based upon the input current flowing in the bit line. The output voltage of the current-to-voltage converter is compared to a reference voltage derived from the output of a reference current-to-voltage converter whose input is driven by a reference current on a reference bit line. Any cell that conducts more current than the reference current will be regarded as an erased cell. Conversely, any cell that conducts less current than the reference current will be regarded as a programmed cell.
