  • ROW ADDRESS CODE SELECTION BASED ON LOCATIONS OF SUBSTANDARD MEMORY CELLS
    Publication number: 20110069572
    Abstract: A memory device identifies memory blocks that contain substandard memory cells. The memory device then determines row address codes to apply to the memory blocks during refresh operations. The row address codes determine which memory blocks of the memory block are refreshed together. The row address codes are designed to ensure that memory blocks having substandard memory cells, which must be refreshed more frequently than other cells, are refreshed together, while memory blocks without substandard memory cells are refreshed together.

  • Apparatus and method for transmitting data using relay station in a broadband wireless communication system
    Patent number: 7912116
    Abstract: A frame configuration method and apparatus for sending data via an RS in a broadband wireless communication system are provided. In the reception mode, the RS monitors reception of data in an (n?1)th frame from an MS and reception of data in an nth frame from a BS. The RS classifies the data received from the MS and the data received from the BS as combinable data to be sent in combination or as non-combinable data to be sent separately, and stores the classified data distinguishably. When the RS transitions to a transmission mode, it determines whether to XOR-operate or mask the stored data. If the stored data can be masked, the RS XOR-operates the stored data and sends the masked data to the BS and the MS.
