Abstract
A method and apparatus to determine a binary signal of a memory cell capable of decreasing an error rate of binary signal determination that occur due to neighboring cells and noise, the apparatus including: a data collection unit to collect target data stored in a target cell in a memory and binary neighboring data of data stored in at least one neighboring cell that neighbors the target cell; a data correction unit to correct the target data collected from the target cell by using the target data and the binary neighboring data collected by the data collection unit and a parameter; and a binary signal determination unit to determine a binary signal of a corrected signal output from the data correction unit.
Claims32
An apparatus to determine a binary signal of a cell in a memory, the apparatus comprising:
- a data collection unit to collect target data stored in a target cell in the memory and binary neighboring data of data stored in at least one neighboring cell that neighbors the target cell;
- a data correction unit to correct the target data collected from the target cell by using the target data and the binary neighboring data collected by the data collection unit and parameter information;
- and
- a binary signal determination unit to determine a binary signal of a corrected signal output from the data correction unit.
A method of determining a binary signal of a cell in a memory, the method comprising:
- collecting target data stored in a target cell in the memory and binary neighboring data of data stored in at least one neighboring cell that neighbors the target cell;
- correcting the target data collected from the target cell by using the collected target data and the binary neighboring data and parameter information;
- and
- determining a binary signal of the corrected data.
An apparatus to correct data of a cell in a memory, the apparatus comprising:
- a data collection unit to collect target data stored in a target cell in the memory and binary neighboring data of data stored in at least one neighboring cell that neighbors the target cell;
- and
- a data correction unit to correct the target data collected from the target cell by using the target data and the binary neighboring data collected by the data collection unit and parameter information.
A memory storing data that is corrected by a correcting apparatus, the memory comprising:
- a target cell storing target data to be corrected by the correcting apparatus;
- at least one neighboring cell storing neighboring data to be used with the target data and parameter information by the correcting apparatus to correct the target data;
- and
- a test area on which the correcting apparatus calculates the parameter information by recording predetermined binary data thereon, reproducing the predetermined binary data therefrom, and comparing the actual predetermined binary data with the reproduced predetermined binary data.
