Abstract
In a memory device, a proportion of at least one cell state in a unit of the memory is determined. A program state of the unit of the memory is determined based on the determined proportion of the at least one cell state. Determining a proportion of at least one cell state in a unit of the memory may be preceded by processing data to be stored in the unit of the memory according to a data value distribution function to produce transformed data having data values conforming to a predetermined distribution and storing the transformed data in the unit of the memory. The distribution function may be configured, for example, to provide a uniform distribution of data values in the unit of the memory.
Claims28
A method of operating a memory comprising a plurality of memory cells, the method comprising:
- determining a proportion of at least one cell state in a unit of the memory;
- determining a program state of the unit of the memory based on the determined proportion of the at least one cell state.
A memory system comprising:
- a memory comprising a plurality cells;
- and
- a program state determiner circuit configured to determine a proportion of at least one cell state in a unit of the memory and to determine a program state of the unit of the memory based on the determined proportion of the at least one cell state.
