Abstract
A device comprises an electronic data memory and a control unit configured to store a bit sequence in the electronic data memory as a stored bit sequence. The control unit is configured to check the stored bit sequence for bit errors, to generate error correction information having information about a correct bit value in the stored bit sequence, and to store the error correction information.
Claims31
A device, comprising:
- an electronic data memory;
- and
- a control unit configured to:
- store a bit sequence in the electronic data memory as a stored bit sequence;
- check the stored bit sequence for bit errors;
- generate error correction information comprising information about a correct bit value in the stored bit sequence;
- and
- store the error correction information, comprising the information about the correct bit value in the stored bit sequence, in the electronic data memory.
5 more elements
A device comprising:
- an electronic data memory configured to store a stored bit sequence;
- and
- a control unit configured to:
- determine stored error correction information assigned to the stored bit sequence, wherein the stored error correction information is stored in the electronic data memory and comprises information about a correct bit value in the stored bit sequence;
- and
- at least partly correct the stored bit sequence using the stored error correction information stored in the electronic data memory to determine a corrected bit sequence.
3 more elements
A method, comprising:
- storing a bit sequence in an electronic data memory as a stored bit sequence;
- checking the stored bit sequence for bit errors;
- generating error correction information comprising information about a correct bit value in the stored bit sequence, wherein the error correction information is indicative of a validity of the error correction information;
- and
- storing the error correction information.
2 more elements
A method, comprising:
- determining stored error correction information assigned to a stored bit sequence, wherein the stored error correction information comprises information about a correct bit value in the stored bit sequence;
- and
- at least one of:
- responsive to a determination that a number of bit errors in the stored bit sequence at least one of exceeds an error correction possibility of a code or can be corrected by the error correction possibility of the code:
- determining, using the stored error correction information, a corrected bit sequence based on the stored bit sequence;
- and
- correcting the corrected bit sequence using the code;
- responsive to a determination that the number of bit errors does not exceed the error correction possibility of the code, correcting the stored bit sequence using the code without using the stored error correction information;
- or
- at least partly correcting the stored bit sequence, independently of an error correction possibility of the code, using the stored error correction information to determine a corrected bit sequence.
