1. A data storage device, comprising:
a memory device; and
a controller coupled to the memory device, wherein the controller is configured to:
perform a read threshold calibration operation on a first page of a plurality of pages of a representative wordline of the memory device to obtain a read threshold of one or more cell states associated with the first page of the representative wordline;
determine one or more physical conditions of the representative wordline; and
generate one or more other read thresholds for one or more other cell states associated with one or more other pages of the representative wordline using a machine learning model based on the read threshold of the one or more cell states associated with the first page of the representative wordline and the one or more physical conditions of the representative wordline.
