Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Memory devices face inefficiencies due to excessive power consumption and thermal issues caused by enabling unnecessary channels, which can lead to performance limitations and application failures, especially as storage capacity increases and data retrieval speed demands rise.
Innovation Solution
A modular channel architecture that dynamically enables or disables channels based on the bandwidth demand of applications, consolidating operations to reduce power usage and temperature by selectively disabling unnecessary channels and shifting operations to other channels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If channels are enabled to provide data to applications, then data access capability is improved, but power consumption increases
Solution Approach 1:
The patent implements dynamic channel management where the controller selectively enables or disables channels based on real-time bandwidth demand. The system transitions from a static all-channels-enabled approach to a dynamic approach where channels are activated only when needed, thereby reducing power consumption while maintaining data access capability when required.
Solution Approach 2:
The system changes the operational state parameter of channels from a fixed enabled state to a variable state that can be enabled or disabled based on bandwidth requirements. This parameter change allows the system to optimize between power consumption and data access capability by adjusting channel states dynamically.
2Speed
If channels are enabled to increase bandwidth, then data retrieval speed is improved, but temperature increases
Solution Approach 1:
The controller dynamically adjusts the number of active channels based on bandwidth demand, enabling more channels when high data retrieval speed is needed and disabling excess channels when bandwidth requirements are low, thereby controlling temperature rise.
Solution Approach 2:
The system periodically monitors bandwidth demand and adjusts channel states accordingly, implementing a cyclical pattern of enabling/disabling channels to maintain optimal temperature while providing high data retrieval speed when needed.
3Productivity
If all channels are enabled to meet application bandwidth demand, then data access performance is improved, but unnecessary channels consume power and resources
Solution Approach 1:
The controller extracts and disables unnecessary channels from the active set, removing only the excess channels while maintaining the required number of channels for meeting bandwidth demand. This selective removal reduces power consumption without compromising data access performance.
Solution Approach 2:
The system implements feedback control where the controller monitors aggregate bandwidth demand and adjusts channel states based on this feedback. When bandwidth demand is low, the controller disables excess channels; when demand increases, it enables additional channels, thereby optimizing power consumption while maintaining performance.
4Use of energy by moving object
If channels are disabled to reduce power consumption, then energy efficiency is improved, but data access capability may be insufficient
Solution Approach 1:
The controller continuously monitors bandwidth demand and uses this feedback to determine when to enable or disable channels. This feedback mechanism ensures that channels are disabled only when bandwidth demand is sufficiently low, preventing data access capability from becoming insufficient while maintaining energy efficiency.
Solution Approach 2:
The system dynamically changes the operational parameter of channels from a static state to a variable state that responds to bandwidth demand, allowing the system to optimize energy efficiency while maintaining adequate data access capability through parameter adjustment.
