Patent ID: 11972820
Assignee: SANDISK TECHNOLOGIES, INC.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A non-volatile storage apparatus, comprising:
data word lines;
one or more control lines;
a plurality of non-volatile memory cells connected to the data word lines and the one or more control lines; and
a control circuit connected to the data word lines and the one or more control lines as well as the memory cells, the control circuit is configured to pre-charge channels of unselected memory cells while lowering voltages at the end of program-verify by applying an overdrive voltage to data word lines between a selected word line and the one or more control lines concurrently with applying a pre-charging voltage to the one or more control lines to provide the channels of the unselected memory cells with access to the pre-charging voltage on the one or more control lines while lowering voltages of data word lines further from the one or more control lines than the selected word line, the control circuit is configured to cut off the channels of the unselected memory cells from the one or more control lines subsequent to the pre-charging and prior to lowering the data word lines between the selected word line and the one or more control lines from the overdrive voltage to one or more voltages below threshold voltages of memory cells connected to the data word lines between the selected word line and the one or more control lines.
