First Claim
Patent Images
1. A method comprising:
- in a data storage device that includes a memory and a controller associated with operation of memory cells of the memory, the data storage device coupled to a three-dimensional memory, performing, in response to a request to read data from the memory, wherein the data is located within a first word line of the memory;
accessing the data from the first word line;
generating a value corresponding to a second word line of the memory;
performing a comparison between the value and a probability threshold; and
determining, based on the comparison, to perform a remedial action with respect to the second word line.

Abstract
A method may be performed in a data storage device that includes a memory including a three-dimensional (3D) memory and a controller, in response to a request to read data from the memory. The data is located within a first word line of the memory. The method includes accessing the data from the first word line and determining, based on a probability threshold, whether to perform a remedial action with respect to a second word line.

15. A data storage device comprising:
-
a memory including a first word line and a second word line; and a controller coupled to a three-dimensional (3D) memory, wherein the controller is associated with operation of memory cells of the memory and is configured, in response to a request to read data from the memory, wherein the data is located within a first word line of the memory, to access the data from the first word line and to generate a value corresponding to the second word line and to perform a comparison between the value and a probability threshold, and wherein the controller is further configured to determine, based on the comparison, to perform a remedial action with respect to the second word line. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
