Abstract
A data storage device includes a non-volatile memory and a controller coupled to the non-volatile memory. The controller is operable to measure a first threshold voltage (VT) of a memory cell under a first parameter at a read temperature and measure a second VT of the memory cell under a second parameter at the read temperature in which the first parameter is different from the second parameter. A VT correction term for the memory cell is determined based upon the first VT measurement and the second VT measurement. A read VT of the memory cell is adjusted by using the VT correction term.
