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, wherein the reading n additional states from further memory cells is performed before, during, or after the determining the n states in a time domain for each of the at least two codes;
- 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, wherein the processing circuit is configured to read n additional states from further memory cells before, during, or after determining the n states in a time domain for each of the at least two codes;
- 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, wherein the means for reading n additional states is operable to read the n additional states before, during, or after the means for determining determines the n states in a time domain for each of the at least two codes;
- 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, wherein the reading n additional states from further memory cells is performed before, during, or after the determining the n states in a time domain for each of the at least two codes;
- and
- taking the at least one reference value as a basis for determining which of the at least two codes is the correct code.
