Solution Overview

Problem

Existing electronic tokens, such as SIM cards, face reduced lifespan due to high temperatures and unpredictable usage patterns, as pre-initialized long life mechanisms cannot be optimized for specific environment conditions and usage scenarios after deployment.

Innovation Solution

An electronic token with a microprocessor, communication interface, and memory that allows for updating its memory lifespan management policy based on data received from a distant machine, enabling customization of wear leveling and memory cell anti-aging mechanisms post-deployment and usage.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wear leveling and memory cell anti-aging mechanisms are pre-initialized during personalization stage, then chip lifespan is extended under usual conditions, but the mechanisms cannot be optimized for specific future usage patterns and environment conditions

Engineering Contradiction:

Improvechip lifespanVSAvoidoptimization for specific usage

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic adaptation of memory lifespan management mechanisms by transitioning from static pre-initialized policies to dynamically adjustable policies that can be modified based on actual usage patterns and environmental conditions detected during operation

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system incorporates feedback mechanisms that monitor actual memory usage patterns and environmental conditions, then use this information to adjust and optimize the wear leveling and anti-aging mechanisms accordingly

Inventive Principle:

Principle #23Feedback

2Reliability

If worst scenario assumptions are used for memory protection, then all memory areas are protected conservatively, but the long life mechanisms remain not optimized since memory usage is not known in advance

Engineering Contradiction:

Improvememory protectionVSAvoidmechanism optimization

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system performs preliminary protective actions during personalization stage but maintains the capability to adjust these actions based on actual usage, avoiding the need to assume worst-case scenarios for all memory areas from the beginning

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent changes the parameters of memory protection mechanisms dynamically based on observed usage patterns and environmental conditions, transitioning from fixed conservative parameters to adaptive parameters that optimize protection efficiency

Inventive Principle:

Principle #35Parameter changes

AI summary

The invention is a method of customizing a memory lifespan management policy of an electronic token. The electronic token is intended to be connected to a device able to establish a wireless channel. The electronic token has a microprocessor, a communication interface, a first memory intended to comprise said memory lifespan management policy, first means for exchanging data with a distant machine by means of a wireless channel established by said connected device, second means for applying said memory lifespan management policy in said electronic token, and third means for updating said memory lifespan management policy. Said method comprises the steps of—sending data from the distant machine to the electronic token by means of a wireless channel,—updating said memory lifespan management policy as a function of data received from said distant machine.
