  • METHOD AND SYSTEM FOR IMPLICIT OR EXPLICIT ONLINE REPAIR OF MEMORY
    Publication number: 20140075093
    Abstract: Systems and methods related to a memory device are provided. The systems and methods include using at least one driver with predetermined reduced driving capability to drive at least one of the memory elements of the memory device in a reliable detection algorithm. The at least one driver has reduced driving capability compared to a driver used for standard read access. The reliable detection algorithm can include detecting failing memory elements on a respective reading current diverging from an expected or expectable reading current.

  • Method for operating memory devices for storing data
    Patent number: 6907544
    Abstract: A storage device is disclosed and is characterized in that the data to be stored therein can be automatically and repeatedly stored in the device and/or in that additional information dependent on the data to be stored therein can be generated and stored in addition to the data to be stored and/or in that the data to be stored can be consecutively read under different conditions. Thus, the data originally stored in the storage device can be rapidly and easily reconstructed.
