Abstract
A memory controller configures a plurality of word lines associated with a respective block of a 3D memory device in a first configuration, where the first configuration includes a set of configuration parameters for each word line of the plurality of word lines determined at least in part on the vertical positions of each word line relative to a substrate of the 3D memory device and, while the plurality of word lines are configured in the first configuration, writes data to and reads data from the respective block. For the respective block, the memory controller: adjusts a first parameter in the respective set of configuration parameters corresponding to a respective word line of the plurality of word lines in response to detecting a first trigger condition as to the respective word line and, after adjusting the first parameter, writes data to and reads data from the respective word line.
