Abstract

A request to perform a program operation at a memory device is received. An entry of a device block record stored at the memory device is determined to be removed based on parameters associated with the program operation and a firmware block record that corresponds to the device block record. The firmware block record tracks the entries of the device block record. The entries of the device block record are associated with blocks of the memory device and identify start voltages that are applied to wordlines of the blocks to program memory cells associated with the wordlines. A command is submitted to the memory device to remove the entry associated with a particular block from the device block record and to make a space available at the device block record for a new entry associated with a new block that is to be written in view of the program operation.
