Abstract
A memory system includes a memory device and a controller. The controller performs multiple read operations on a target block, using a first duster of read threshold voltages. The controller generates a second duster of read threshold voltages using the first cluster when a difference between the maximum number of fail bits and the minimum number of fail bits associated with the multiple read operations exceeds a threshold. The controller splits pages in the target block into a first group of pages for the first cluster and a second group of pages for the second cluster. The controller performs additional read operations on the first group of pages using the first cluster and on the second group of pages using the second cluster.
