Abstract
A method and associated apparatus to determine a reference value on the basis of a plurality of half reference values stored in memory cells is disclosed, wherein the plurality of half reference values are read from the memory cells, wherein a subset of half reference values is determined from the plurality of half reference values, and wherein the reference value is determined on the basis of the subset of half reference values.
Claims20
A method for determining a reference value on the basis of a plurality of half reference values stored in memory cells,
- wherein the plurality of half reference values are read from the memory cells,
- wherein a subset of read half reference values is determined from an evaluation of the plurality of read half reference values, wherein the subset of read half reference values comprises fewer than all of the half reference values,
- wherein the reference value is determined on the basis of the subset of half reference values.
A device for determining a reference value on the basis of a plurality of half reference values stored in memory cells, comprising:
- a processing unit configured to:
- determine a subset of a plurality of half reference values read from the memory cells, wherein the subset comprises fewer than all of the half reference values, and
- determine the reference value on the basis of the subset of the half reference values.
A non-transitory computer program product loadable directly into a memory of a digital computer, comprising program code parts suitable for carrying out steps of the method, comprising:
- determining a reference value on the basis of a plurality of half reference values stored in memory cells,
- wherein the plurality of half reference values are read from the memory cells,
- wherein a subset of read half reference values is determined from an evaluation of the plurality of half reference values, wherein the subset of read half reference values comprises fewer than all of the half reference values,
- wherein the reference value is determined on the basis of the subset of half reference values.
A non-transistory computer-readable memory medium comprising instructions which are executable by a computer and which are suitable for the computer to carry out the method, comprising:
- determining a reference value on the basis of a plurality of half reference values stored in memory cells,
- wherein the plurality of read half reference values are read from the memory cells,
- wherein a subset of read half reference values is determined from an evaluation of the plurality of half reference values, wherein the subset of read half reference values comprises fewer than all of the half reference values,
- wherein the reference value is determined on the basis of the subset of half reference values.
