    摘要: A memory device comprises a memory cell array (1) with a multitude of memory cells (111). Each of the memory cells (111) is assigned to one of a multitude of blocks (15). Each memory cell (111) is accessible by an access signal in order to alter stored information. Each of the memory cells (111) is assigned to one of a multitude of blocks (15). The memory device further comprises a measuring unit (100) coupled to the memory cell array (1) and being operable to identify a selected access characteristic of each of the memory cells (11) and an assignment unit (150) which is coupled to the measuring unit (100) and is operable to assign a performance parameter (215) to each block (15). A performance memory unit (2) is adapted to contain the performance parameters (215) assigned to the blocks (15).

    摘要: A method, a memory device and a test unit to test such memory device is provided. The memory device comprises a memory cell array including a multitude of memory cells each having a variable characteristic. The method comprises identifying the characteristic of each memory cell and assigning memory cells of the multitude of memory cells to a weak group in dependence on the identified characteristic. Then the stored information of the memory cells assigned to the weak group is restored in order to modify the characteristics of these memory cells.
