Flash Memory Device With Increase Of Efficiency During An Apde (Automatic Program Disturb After Erase) Process

US Patent:

6469939, Oct 22, 2002

Filed:

Oct 1, 2001

Appl. No.:

09/969572

Inventors:

Zhigang Wang - San Jose CA
Richard Fastow - Cupertino CA
Sameer S. Haddad - San Jose CA
Chi Chang - San Jose CA

Assignee:

Advanced Micro Devices, Inc. - Sunnyvale CA

International Classification:

G11C 1604

US Classification:

36518528, 36518533

Abstract:

A source resistor or a positive voltage is coupled to the source and a negative bias voltage is applied at the substrate or p-well of flash memory cells for enhanced efficiency during programming and/or during an APDE (Automatic Program Disturb after Erase) process for a flash memory device. Furthermore, in a system and method for programming the flash memory device, a flash memory cell of the array of multiple flash memory cells is selected to be programmed. A control gate programming voltage is applied to the control gate of the selected flash memory cell, and a bit line programming voltage is applied to the drain of the selected flash memory cell via the common bit line terminal to which the drain of the selected flash memory cell is connected.
