    摘要: In order to recover phase information, data transmitted at a first frequency is over-sampled using a clock at a second frequency, n times per bit time to obtain n samples. The n samples are used to detect the transitions between two logic levels in said transmitted data which are stored in groups of m sets of said n edge results which are, in turn output at a clock frequency which is the second frequency divided by m, for further processing.

    摘要: A concurrent asynchronous USB 2.0 data stream destuffer and separator with variable-width bit-wise memory controller is described. A parallel stream bit destuffer module identifies in parallel one or more stuffed bits in a decoded data field of a received data stream using a six-bit sliding window. The stuffed bits are bits that were inserted into the received USB data stream by a transmitter to force data transitions in the received USB data stream. A data separator module separates the one or more stuffed bits from a plurality of valid data bits in the decoded data field. A memory module generates an incremental pointer value representative of the number of valid bits and writes the plurality of valid data bits from the decoded data field into a variable sized bit-wise memory structure.

    摘要: Incoming serial data which is received M bits at a time where M=N, N+1 or N−1 and N is greater than 1 is synchronized to a local clock by receiving a first M bits of data, storing the first M bits, receiving M additional bits, storing the M additional bits, repetitively receiving and storing until at least a predetermined number R of bits have been stored, where R=(M*X)+1 where X is an integer greater than one. When this occurs, the first R bits are output and any remaining S bits in excess of R are stored and additional groups of M bits added, with the process continuing until all of a packet has been received. With this arrangement, the R bits may be output at a rate which is a fraction of the serial bit rate.

    摘要: Briefly, voltages to write a memory cell are adjusted if the memory cell is determined to be imprinted. In one embodiment, a positive voltage not including zero is applied to one of a bit line and a word line and a negative voltage not including zero is applied to another of the bit line and the word line to write a specified logic state to an imprinted memory cell. Neighboring cells do not receive disturb voltages in excess of a disturb voltage threshold.

    摘要: Briefly, one or more memory access parameters used to access a memory cell are adjusted based on a sensed operating temperature. In one embodiment, a pulse width of an access voltage is increased as the operating temperature decreases below a threshold. In another embodiment, a drive voltage is decreased as the operating temperature increases.
