  • Memory read-out
    Patent number: 8589765
    Abstract: A memory system having a plurality of memory cells for storing payload data and redundancy data. The memory system having a read-out circuit configured to read-out a status of the plurality of memory cells, the read-out status having payload data, redundancy data and associated reliability information. Moreover, the memory system has a data processor configured to derive the payload data from the read-out status using the reliability information.
    Type: Grant

  • Memory Cell Arrangement and Method for Reading State Information From a Memory Cell Bypassing an Error Detection Circuit
    Publication number: 20090282308
    Abstract: In an embodiment, an integrated circuit having a memory cell arrangement is provided. The memory cell arrangement may include at least one memory cell, at least one error detection circuit, and a controller configured to control a read operation to read state information from the at least one memory cell by reading a memory cell state information bypassing the at least one error correction circuit, or by reading the memory cell state information and supplying it to the at least one error correction circuit.
