1. A method comprising:
- determining a block identifier of a physical block of a memory that is to be accessed;
determining a word line index of a first word line that is to be accessed within the physical block based on the block identifier and further based on a first position of the first word line within the physical block, wherein the word line index is associated with a physical location of the first word line within the memory;
selecting a first value of a first parameter according to a first group of word lines that is associated with the word line index; and
accessing the first word line using the first value of the first parameter, wherein the first group of word lines includes the first word line and also includes a second word line within a second physical block, wherein a second group of word lines includes a third word line within the physical block and also includes a fourth word line at the first position within the second physical block, and wherein the second group of word lines corresponds to a second value of the first parameter that is different than the first value of the first parameter.

Abstract
A method includes determining a block identifier of a physical block of a memory array that is to be accessed. The method further includes determining a word line index of a first word line that is to be accessed within the physical block based on the block identifier and further based on a first position of the first word line within the physical block. The method further includes selecting a first value of a first parameter according to a first group of word lines that is associated with the word line index and accessing the first word line using the first value of the first parameter.

11. A data storage device comprising:
-
a memory; and a controller, wherein the controller is coupled to the memory, and wherein the controller is configured to determine a block identifier of a physical block of the memory to be accessed and to determine a word line index of a first word line that is to be accessed within the physical block based on the block identifier and further based on a first position of the first word line within the physical block, wherein the word line index is associated with a physical location of the first word line within the memory, wherein the controller is further configured to select a first value of a first parameter according to a first group of word lines that is associated with the word line index and to access the first word line using the first value of the first parameter, wherein the first group of word lines includes the first word line and also includes a second word line within a second physical block, wherein a second group of word lines includes a third word line within the physical block and also includes a fourth word line at the first position within the second physical block, and wherein the second group of word lines corresponds to a second value of the first parameter that is different than the first value of the first parameter. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
