Title:
DEVICE AND METHOD FOR CLOSING INTERNAL MODES/FUNCTIONS OF INTEGRATED CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2008/028401
Kind Code:
A1
Abstract:
A device and method for closing internal modes/functions of an integrated circuit, wherein
the method comprises the steps of: writing a plurality of predetermined mode/function
feature values respectively corresponding to multiple mode/function circuits
in the nonvolatile memory of the integrated circuit, and storing it in the nonvolatile
memory of the integrated circuit; the mode/function circuits in the integrated
circuit adopting hierarchical resetting, and the mode/function feature values
in the nonvolatile memory of the integrated circuit are verified one by one during
the hierarchical resetting, and a corresponding operation is determined based
on the result of the verification of the mode/function feature values in the nonvolatile
memory.
