    摘要: A multiport interface for digital communication systems having pipelined multiplexing of port instructions for increased throughput. The multiport interface includes an analog delay for independent timing of asynchronous operations, such as memory accesses. The multiport interface also has an instruction pipeline and multiplexer to coordinate a number of port instructions.

    摘要: An ATM switch including a multi-port memory is described. The multi-port memory having a dynamic random access memory (DRAM) and a plurality of input and output serial access memories (SAMs). Efficient, flexible transfer circuits and methods are described for transferring ATM data between the SAMs and the DRAM. The transfer circuits and methods include helper flip/flops to latch ATM data for editing prior to storage in the DRAM. Editing of ATM data transferred from the DRAM is also described. Dynamic parity generation and checking is described to detect errors induced during switching.

    摘要: Methods, systems, and apparatus for testing semiconductor devices. A semiconductor device includes one or more external terminals configured to receive fuse configuration data from an external source. The semiconductor device also includes a soft-blow circuit to generate a soft-blow signal based on the fuse configuration data, and a fuse circuit that includes a fuse and has first and second operational states corresponding to the fuse being intact and blown, respectively. The fuse circuit is configured to receive the soft-blow signal and to select its operational state to be the first or second operational state based on the received soft-blow signal.
