Abstract
Disclosed herein are related to a system and a method for adjusting a read voltage threshold to read data from a plurality of memory dies of a nonvolatile memory device. Each of the plurality of memory dies comprises a plurality of blocks. A controller in communication with the plurality of memory dies may read, from a first block of the plurality of blocks, data corresponding to a read command received from a host. The controller may determine a bit error rate for the first block based on the data. The controller may update the read voltage threshold for the first block when the bit error rate for the first block exceeds a first error threshold. The read voltage threshold may be stored in the controller.
