Abstract
Disclosed is a system and method for adjusting read levels in a storage device based on bias functions. The method includes receiving a request to perform a memory access operation on a wordline of non-volatile memory. The method also includes selecting a bias function corresponding to the wordline of the non-volatile memory from a group of bias functions. The method also includes determining a bias value based on the selected bias function and the wordline. The method also includes adjusting a read level in the non-volatile memory based on the bias value. The method also includes performing the memory access operation on the wordline of the non-volatile memory using the adjusted read level. The bias functions may be linear functions and adjusted in response to detecting a recalibration condition.
