Abstract:
1. A method comprising: determining a value of a first parameter for a first word line within a first physical block of a memory; comparing the value to a set of values including a first value of the first parameter and a second value of the first parameter; associating the first word line with the first value in response to determining that a first difference between the value and the first value is less than a second difference between the value and the second value; determining a block identifier of the first physical block; determining a word line index of the first word line based on the block identifier and further based on a first position of the first word line within the first physical block, wherein the word line index is associated with a first physical location of the first word line within the memory; and accessing the first word line using the first value of the first parameter, wherein a first group of word lines that is associated with the word line index includes the first word line and also includes a second word line within a second physical block of the memory, wherein a second group of word lines includes a third word line within the first 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 the second value.
