  • Patent number: 8422271
    Abstract: Method and apparatus for transferring data in a memory. A semiconductor memory includes a plurality of memory cells each having a resistive sense element (RSE) in series with a switching device. A conductive word line extends in a first direction adjacent the memory cells and is connected to a gate structure of each of the switching devices. A plurality of conductive bit lines extend in a second direction adjacent the memory cells, each bit line providing a connection node that interconnects a respective pair of the memory cells. A control circuit senses a programmed state of a selected memory cell by setting each of the bit lines on a first side of the selected memory cell to a first voltage level, setting each of the remaining bit lines on an opposing second side of the selected memory cell to a second voltage level, and setting the word line to a third voltage level.

  • Patent number: 8402352
    Abstract: Exemplary embodiments for providing multi-bit error correction based on a BCH code are provided. In one such embodiment, the following operations are repeatedly performed, including shifting each bit of the BCH code rightward by 1 bit while filling the bit vacated due to the rightward shifting in the BCH code with 0, calculating syndrome values corresponding to the shifting of the BCH code, and determining a first error number in the BCH code under the shifting based on the syndrome values corresponding to the shifting of the BCH code. In the case where the first error number is not equal to 0, modified syndrome values are calculated corresponding to the shifting of the BCH code. The modified syndrome values are those corresponding to the case that the current rightmost bit of the BCH code under the shifting is changed to the inverse value. Additional operations are performed as described herein.

  • Patent number: RE44661
    Abstract: A protection CMTS is available to immediately service a cable modem should that modem's service from a working CMTS fail for any reason. To speed the service transfer (cutover) from the working CMTS to the protection CMTS, the cable modem may preregister with the protection CMTS well before the cutover becomes necessary. The cable modem's registration with both the working CMTS and the protection CMTS preferably employs a single IP address, so that the cable modem need not obtain a new IP address during cutover. While the cable modem may register with both the working CMTS and the protection CMTS, the devices are designed or configured so that only the working CMTS injects a host route for the cable modem into the appropriate routing protocol. Only after cutover to the protection CMTS does the protection CMTS inject its host route.
