Abstract
A system can include a memory device and a processing device, operatively coupled with the memory device, to perform operations including receiving data to be stored on the memory device, storing a first copy of the data in a first set of memory cells of the memory device, and storing a second copy of the data in a second set of memory cells of the memory device. The operations can also include reading the first copy of the data and determining whether a threshold voltage of a cell in the first set of memory cells is within an overlapping range of voltage distributions, and reading the second copy of the data and determining whether the threshold voltage of a cell in the second set of memory cells is within an overlapping range of voltage distributions. They can also include using the second copy of the data.
