Abstract
An apparatuses and methods for inferring threshold voltage distributions associated with memory cells via interpolation. A determining soft data for a group of memory cells each programmed to one of a number of data states, wherein the soft data comprises a number of different soft data values, determining a quantity of memory cells associated with each of the different soft data values, and inferring at least a portion of a threshold voltage distribution associated with the group of memory cells via an interpolation process using the determined quantities of memory cells associated with each of the different soft data values.
