Abstract
A method for detecting a code word is proposed, wherein the code word is a code word of one of at least two codes, wherein n states are read from memory cells of a memory, respectively. The n states are determined in a time domain for each of the at least two codes, wherein additionally n states are read from further memory cells and at least one reference value is determined therefrom and wherein the at least one reference value is taken as a basis for determining which of the at least two codes is the correct code. A corresponding device is furthermore specified.
Claims18
A method for detecting a code word, wherein the code word is a code word of one of at least two codes, comprising:
- reading n states from memory cells of a memory, respectively;
- determining the n states in a time domain for each of the at least two codes;
- reading n additional states from further memory cells, respectively, and determining at least one reference value therefrom;
- and
- taking the at least one reference value as a basis for determining which of the at least two codes is the correct code.
A device for detecting a code word, wherein the code word is a code word of one of at least two codes, comprising a processing circuit configured to:
- read n states from memory cells of a memory, respectively;
- determine the n states in a time domain for each of the at least two codes;
- read n additional states from further memory cells, respectively, and determining at least one reference value therefrom;
- and
- take the at least one reference value as a basis for determining which of the at least two codes is the correct code.
A device for detecting a code word, wherein the code word is a code word of one of at least two codes, comprising:
- means for reading n states from memory cells of a memory, respectively;
- means for determining the n states in a time domain for each of the at least two codes;
- means for reading n additional states from further memory cells and for determining at least one reference value on the basis of the states read from the further memory cells;
- and
- means for determining which of the at least two codes is the correct code on the basis of the at least one reference value.
A non-transitory computer readable storage medium containing instructions which are loadable into a memory of a digital computer, wherein such instructions, upon execution, are suitable for carrying out a method, comprising:
- reading n states from memory cells of a memory, respectively;
- determining the n states in a time domain for each of the at least two codes;
- reading n additional states from further memory cells, respectively, and determining at least one reference value therefrom;
- and
- taking the at least one reference value as a basis for determining which of the at least two codes is the correct code.
