Abstract
The present disclosure includes apparatuses and methods for determining soft data for combinations of memory cells. A number of embodiments include an array of memory cells, wherein the array includes a first memory cell and a second memory cell, wherein the first and second memory cells are each programmable to one of a number of program states, and wherein a combination of the program states of the first and second memory cells corresponds to one of a number of data states. A number of embodiments also include a buffer and/or a controller coupled to the array and configured to determine soft data associated with the program states of the first and second memory cells and determine soft data associated with the data state that corresponds to the combination of the program states of the first and second memory cells based, at least in part, on the soft data associated with the program state of the first memory cell and the soft data associated with the program state of the second memory cell.
