Abstract
Recovering data from a faulty memory block in a memory system. Various methods include: reading a target word line in a memory block to obtain a first data; determining the first data has an uncorrectable error; and then adjust bias parameters of a first group of neighboring word lines within the memory block, where adjusting bias parameters creates a first adjusted bias parameters; and reading the target word line using the adjusted bias parameters to obtain second data from the target word line. The method also includes determining the second data has a second uncorrectable error; and then adjusting bias parameters of a second group of lines within the memory block, where adjusting the bias parameters of the second group creates second adjusted bias parameters; and reading the target word line using the first and second adjusted bias parameters to obtain a third data from the target word line.
