Solution Overview

Problem

Conventional methods for adjusting the operating frequency of a memory in electronic devices require users to shut down and restart the device, making the process inconvenient, inefficient, and only suitable for professionals, as it cannot be performed during operation and is manually intensive.

Innovation Solution

A method and electronic device configuration that allows dynamic adjustment of memory frequency during operation by transmitting specific commands to the memory controller and memory, enabling automatic frequency adjustment based on system resource usage or central processor frequency changes, without requiring user intervention or device restart.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the conventional method of adjusting memory frequency is used, then the memory frequency can be adjusted, but the electronic device must be shut down and restarted, making the process inconvenient and time-consuming

Engineering Contradiction:

Improveconvenience of frequency adjustmentVSAvoidtime required for adjustment process

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent applies the dynamics principle by enabling the memory frequency to be adjusted dynamically during the electronic device's operation rather than requiring a static restart. The frequency controller can change the memory operating frequency in real-time based on system needs, transforming a static adjustment process into a dynamic one that occurs without interrupting normal device functionality.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The patent implements preliminary action by having the frequency controller prepare and execute frequency adjustment commands before the user actually needs to adjust the frequency. The system can proactively adjust frequencies based on predicted usage patterns or system state, avoiding the need for users to manually initiate the adjustment process through shutdown and restart procedures.

Inventive Principle:

Principle #10Preliminary action

2Extent of automation

If manual frequency adjustment is used, then the frequency can be changed, but it requires user intervention and is not convenient or intelligent

Engineering Contradiction:

Improveautomatic frequency adjustmentVSAvoiduser convenience

Core Design Contradiction:

Extent of automationVSEase of operation

Solution Approach 1:

The patent applies the self-service principle by enabling the frequency controller to automatically adjust memory frequencies without requiring user intervention. The system monitors its own operational state and autonomously determines optimal frequency settings, making the adjustment process self-contained and eliminating the need for users to manually configure frequency parameters.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent implements feedback by having the frequency controller continuously monitor system performance and resource usage, then adjust memory frequencies based on this feedback information. The system learns from operational patterns and automatically optimizes frequencies to match actual usage needs, creating an intelligent adaptive adjustment mechanism.

Inventive Principle:

Principle #23Feedback

3Manufacturing precision

If professional adjustment methods are used, then the frequency can be adjusted accurately, but the process is complex and only suitable for professionals

Engineering Contradiction:

Improvefrequency adjustment precisionVSAvoidcomplexity of adjustment process

Core Design Contradiction:

Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent applies the intermediary principle by introducing a frequency controller as a specialized component that mediates between the user's frequency adjustment needs and the complex underlying hardware configuration. This intermediary handles the complexity of frequency coordination between different system components, presenting a simplified interface to users while maintaining precise control over the actual frequency adjustment process.

Inventive Principle:

Principle #24Intermediary (Mediator)

4Productivity

If the electronic device is restarted to adjust frequency, then the memory can operate at a new frequency, but the adjustment process is tediously long

Engineering Contradiction:

Improveefficiency of frequency adjustmentVSAvoidadjustment process duration

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The patent applies the continuity of useful action principle by maintaining continuous operational functionality during frequency adjustment. Instead of interrupting the device to restart and reconfigure, the frequency controller adjusts memory frequencies while the device continues to operate normally, ensuring that useful actions are not interrupted and productivity is maintained throughout the adjustment process.

Inventive Principle:

Principle #20Continuity of useful action

AI summary

Methods and electronic devices for adjusting an operating frequency of a memory are disclosed. The method includes: transmitting to the memory a first command that instructs the memory to hold the data information in the memory; transmitting to the memory controller a second command that adjusts the first frequency of the memory controller to a second frequency; and transmitting to the memory a third command that instructs the memory to exchange the data information according to the second frequency of the memory controller. According to the disclosure, it is possible to dynamically adjust the frequency of the memory during operation, avoiding the need of the user to turn off and then turn on the electronic device to adjust the frequency of the memory.
