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.

Memory read-out

In an embodiment, an integrated circuit having a memory cell arrangement is provided. The memory cell arrangement may include a memory cell block having a plurality of memory cells, a storage portion configured to store information about a quality characteristic of the memory cells of the memory cell block, and a controller configured to control a read operation, and to change the information about the quality characteristic depending on a quality of a read operation.
