Abstract
Provided is a method for operating a nonvolatile memory device. In the method, read data is read by means of a read level and logic values for erasure-decoding the read data are set. The bits of the read data corresponding to the range of the set logic values is set as erasure bits, and an erasure decoding operation is performed.
Claims18
A method for operating a nonvolatile memory device, comprising:
- reading data using a read level;
- setting a range of logic values for erasure-decoding the read data;
- setting bits of the read data, corresponding to the set range of logic values, as erasure bits;
- and
- performing an erasure decoding operation.
2 more elements
A nonvolatile memory device comprising:
- a read/write circuit configured to read data from memory cells of a memory cell array using a read level to determine first and second logic states of the memory cells of the memory cell array;
- and
- a control logic circuit configured to detect the read level for erasure-decoding the read data;
- wherein
- the control logic circuit is further configured to set a range of logic values for the erasure decoding operation and configured to set bits of the read data, corresponding to the set range of logic values, as erasure bits.
2 more elements
A memory system comprising:
- a nonvolatile memory device configured to read data from memory cells of a memory cell array using a read level for determining first and second logic states of the memory cells;
- and
- a controller configured to control the nonvolatile memory device to detect the read level and erasure-decode the read data;
- wherein
- the controller is further configured to set a range of logic values for erasure decoding the read data and configured to set bits of the read data, corresponding to the set range of logic values, as erasure bits.
