US Patent:

6456529, Sep 24, 2002

Filed:

Sep 27, 2001

Appl. No.:

09/967513

Inventors:

James D. Sansbury - Portola Valley CA
Sau C. Wang - Hillsborough CA

Assignee:

SanDisk Corporation - Sunnyvale CA

International Classification:

G11C 1604

US Classification:

3651851, 36518503, 36518501

Abstract:

A programmable impedance element ( ) is implemented using integrated circuit techniques and devices. An impedance of the programmable impedance element is adjusted by appropriately configuring the element. The programmable impedance element has a range of impedance values, and is configurable to be a value within this range. In an embodiment, the programmable impedance element is implemented using a floating gate device ( ), and is nonvolatile.
