Abstract:
A memory device includes a first pillar coupled with a first data line, a second pillar coupled with a second data line, and wordlines coupled with first and second pillars. Control logic may cause wordlines to be discharged after a program pulse is applied to selected wordline. The control logic may apply a supply voltage to second data line to cause a voltage of second pillar to float. The control logic may apply a ground voltage to the first data line to inhibit soft erase associated with the selected wordline via first pillar.
