Abstract: A memory system includes a memory array for storing a plurality of data elements, the memory array comprising a plurality of memory blocks. In one embodiment, the data element are tag string data. The memory system may also include a comparator unit coupled to receive a memory block output and an input signal, wherein when the memory block output matches the input signal, the memory system transmits a match signal and a code word on a result bus. In one embodiment, data elements are stored as fragments in different portions of the memory array. The input signal may be received as fragments and compared to the data elements over different time periods. In one embodiment, the present invention provides a memory lookup system and method that supports multiple protocols.

Abstract: One embodiment of the invention includes a transformer that is at least partially formed on a substrate. The transformer is for electrical isolation and signal filtering. The transformer includes the following elements. A portion of the substrate has two holes through the substrate. A ferrite core is formed in a loop through the two holes. A primary winding is made of a first metal trace. The first metal trace is formed in a spiral around one hole. The first metal trace has at least two primary terminals acting as an input to the transformer. The transformer also includes a secondary winding. The secondary winding is made of a second metal trace. The second metal trace is formed in a spiral around the other hole. The second metal trace has at least two secondary terminals acting as an output from the transformer.

Abstract: A flyback converter using a commercially available voltage regulator with protection mode includes a bypass resistor between the input and output of the voltage regulator to drain charge from the input stage during powerup thereby preventing the regulator from locking in protection mode.
