  • Patent number: 7684277
    Abstract: Embodiments of the invention provide a memory device comprising a non-volatile memory element, a read-out circuit for reading out an item of memory information stored in the memory element, a switching unit, by means of which a supply voltage can be applied to the read-out circuit, and a control unit, which has the capability of controlling the switching unit in a manner dependent on the memory information stored in the memory element.

  • Patent number: 7627792
    Abstract: A method for repairing a memory comprising a Memory Built-In Self Repair (MBISR) structure comprises the steps of detection of defective storage cells, and redundancy allocation. The redundancy allocation step is carried out in such a way that it combines a row and/or column oriented redundancy repair approach with a word oriented redundancy repair approach. A Memory Built-In Self Repair (MBISR) device comprises at least one memory (2) with row and/or column redundancy, at least one row and/or column Memory Built-In Self Repair (MBISR) circuit (3), and a word redundancy block (4). Furthermore, a distributed MBISR structure as well as dedicated Column/Row MBISR circuits (3) are provided.

  • Patent number: 7237153
    Abstract: An integrated memory and method for testing an integrated memory is provided herein. In order to test an integrated memory having a main data memory with a plurality of data memory units, a data memory unit is addressed and input test data for testing the addressed data memory unit are applied to the main data memory. The output test data are read out from the main data memory and compared with expected desired output test data in a self-test unit. Deviations detected during the comparison are buffer-stored in a redundancy analysis memory. These information items buffer-stored in the redundancy analysis memory are read out and transferred to a computing unit. In the computing unit, the defect positions in the output test data are identified, and a repair strategy is determined by means of redundant rows and/or redundant columns and/or redundant words provided. The redundant words required for the repair strategy are written to the redundancy analysis memory and activated.

  • Publication number: 20050066224
    Abstract: A correcting device (6) with substitute memory words (8) which take on the function of memory words identified as defective in the memory (1) is assigned for correcting the errors of a digital memory (1). Memory access to memory words of the memory (1) identified as defective is for this purpose diverted to corresponding substitute memory words (8). According to the invention the memory (1) has different lines (2, 3) for reading and for writing, wherein when there is write access a value written into a memory word via an input line (2) is read out again and appears on the output line (3) (write-through memory). Each time there is write access to a memory word of the memory (1) the written value is compared with the value output via the output line (3) and if there is incorrect agreement the corresponding memory word is identified as defective.

  • Publication number: 20040153925
    Abstract: An integrated memory and method for testing an integrated memory is provided herein. In order to test an integrated memory having a main data memory (SP) with a plurality of data memory units, a data memory unit is addressed and input test data for testing the addressed data memory unit are applied to the main data memory (SP). The output test data are read out from the main data memory (SP) and compared with expected desired output test data in a self-test unit (STE). Deviations detected during the comparison are buffer-stored in a redundancy analysis memory (RAS). These information items buffer-stored in the redundancy analysis memory (RAS) are read out and transferred to a computing unit (RE). In the computing unit (RE), the defect positions in the output test data are identified, and a repair strategy is determined by means of redundant rows and/or redundant columns and/or redundant words provided.
