Abstract
The present disclosure includes methods, devices, and systems for determining and using soft data in memory devices and systems. One or more embodiments include an array of memory cells and control circuitry coupled to the array. The control circuitry is configured to perform a number of sense operations on the memory cells using a number of sensing voltages to determine soft data associated with a target state of the memory cells, and adjust a sensing voltage used to determine the target state based, at least partially, on the determined soft data.
Claims20
A memory device, comprising:
- a number of memory cells;
- and
- control circuitry coupled to the memory cells and configured to:
- determine soft data associated with a target state of the memory cells;
- and
- adjust a sensing voltage used to determine the target state based, at least partially, on the determined soft data.
A method for operating a memory device, comprising:
- determining soft data associated with a target state of a number of memory cells;
- performing an error correction operation on the soft data;
- and
- adjusting a sensing voltage used to determine the target state based, at least partially, on a result of the error correction operation.
A memory device, comprising:
- a number of memory cells;
- and
- control circuitry coupled to the memory cells and configured to:
- determine soft data associated with a target state of the memory cells;
- perform an error correction operation on the soft data;
- and
- adjust a sensing voltage used to determine the target state upon the error correction operation not resulting in a failure.
