Storage Controller Dynamic Timing Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current data storage devices, such as SSDs and memory cards, face inefficiencies in data transfer operations due to fixed timing protocols that do not adapt to varying data transfer patterns, leading to suboptimal performance and input/output delays.
Innovation Solution
A controller with a firmware system that generates transfer pattern information by monitoring data transfer statuses and adjusts operation timing to optimize data transfer operations, using modules for transfer pattern generation, operation timing setting, and control signal generation to synchronize data transfers with host device commands.

Engineering Contradiction Analysis
1Productivity
If fixed timing protocols are used for data transfer operations, then device complexity is reduced and ease of operation is improved, but data transfer performance deteriorates and input/output delays increase
Solution Approach 1:
The patent implements dynamic timing adjustment by monitoring data transfer patterns and adapting operation timing accordingly. The controller transitions from fixed timing protocols to dynamic timing adjustment, where operation timing is continuously optimized based on observed transfer patterns, thereby improving data transfer performance without requiring overly complex predetermined timing schemes
Solution Approach 2:
The patent employs feedback mechanisms where the controller monitors data transfer statuses and uses this information to adjust operation timing. The transfer pattern information generated from monitoring serves as feedback that drives timing optimization, creating a closed-loop system that improves performance while maintaining manageable complexity through adaptive rather than purely predetermined control
2Productivity
If fixed timing protocols are used for data transfer operations, then device complexity is reduced, but input/output efficiency deteriorates and delays increase
Solution Approach 1:
The controller dynamically adjusts operation timing based on monitored transfer patterns, transitioning from static fixed timing to adaptive timing. This dynamic adjustment reduces input/output delays by optimizing timing parameters according to actual transfer patterns, thereby improving input/output efficiency without requiring excessive complexity
Solution Approach 2:
The patent changes timing parameters dynamically based on transfer pattern information. By adjusting operation timing parameters according to observed data transfer patterns, the system optimizes input/output efficiency and reduces delays while maintaining manageable device complexity through parameter adaptation rather than structural complexity

AI summary
A controller for controlling an operation of a data storage device may include: a host interface configured to perform data communication with a host device; a memory configured to store firmware for controlling an operation of the host interface; and a processor configured to load the firmware to control the operation of the host interface. The firmware may generate transfer pattern information regarding previous data transfer operations by monitoring a data transfer status between the host interface and the host device, adjust an operation timing of the host interface based on the generated transfer pattern information, and control the host interface to perform a current data transfer operation according to the adjusted operation timing.
