US Patent:

8294940, Oct 23, 2012

Filed:

May 29, 2008

Appl. No.:

12/129076

Inventors:

Walter Lee McNall - Meridian ID, US
Randall D. Briggs - Boise ID, US

Assignee:

Marvell International Ltd.

International Classification:

G06K 15/00
G06F 3/12

US Classification:

358 116, 358 113

Abstract:

A system and method are disclosed for updating data stored in a one-time programmable (non-rewritable) non-volatile storage device (“OTP”). The OTP is segmented so that updated data may be written to unused areas. Valid data may be differentiated from stale data using a data recognition technique such as tallying or indexing. According to a tallying technique, an updated event count may be obtained by counting the number of blown bits in the OTP. Each time the event occurs, the next bit is blown. According to an indexing technique, each bit in an index corresponds to a data block in the OTP. When updated data is written to the next (empty) data block in order in the OTP, the corresponding (next) index bit is blown. A valid data set may be located by counting the number of blown bits in the index.

International Classification:

H03L 7/081

US Classification:

331 25, 327161, 327291, 331 1 R

Abstract:

An integrated circuit has operational circuitry to perform an operation. An operational regulator regulates an operating condition of the operational circuitry. The operational regulator has a sample clock to generate a sample clock signal. The sample clock signal correlates to a manufacturing variation of the electronic circuitry. The operational regulator also includes a configurator to evaluate the sample clock signal and generate a configuration signal according to the evaluation. A controller is provided to receive the configuration signal and control an operating condition of the operational circuitry according to the configuration signal.

International Classification:

H01L 21/268

H03K 19/177

US Classification:

326 8, 438795, 438467

Abstract:

The present disclosure describes apparatuses and techniques for device-based die authentication. In some aspects, an intensity of a particle beam is varied during semiconductor processing to provide a semiconductor die having devices of varied values. In other aspects, different areas of semiconductor dies are exposed during semiconductor processing to provide semiconductor dies with devices that vary in value from one die to the next. For each semiconductor die, a value generated based on the values of the die's respective devices can be associated with that die thereby enabling subsequent authentication of the semiconductor die.
