Abstract
A non-volatile storage apparatus includes non-volatile memory cells, word lines connected to the non-volatile memory cells, and a control circuit connected to the word lines and the memory cells. The word lines include data word lines and dummy word lines. Memory cells connected to data word lines are configured to store host data. Memory cells connected to dummy word lines do not store host data. The control circuit is configured to erase, program and read the memory cells. Errors from threshold voltage up-shifting in the memory cells connected to dummy word lines is prevented by adjusting the voltage applied to dummy word lines.
