Assignee: WESTERN DIGITAL TECHNOLOGIES, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 18:
19. The data storage device of claim 18, wherein the controller is further configured to either:
option 1:
reset the first FBC equal to the second FBC when the second FBC is determined to be less than the first FBC;
decrease a read threshold voltage of a second state of the second page by the voltage shift; and
re-compare the second FBC to the first FBC, wherein the second FBC corresponds to a FBC of the second page at the decreased read threshold voltage of the second state; or

option 2:
increase the decreased read threshold voltage of the first state of the second page by the voltage shift;
decrease the read threshold voltage of the second state of the second page by the voltage shift; and
re-compare the second FBC to the first FBC, wherein the second FBC corresponds to a FBC of the second page at the decreased read threshold voltage of the second state.
