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.
