Portable Terminal Memory Region Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Portable terminals face inefficiencies in memory management, particularly in non-volatile memory, where users must delete data to make space for new entries, and backing up data often results in format changes, causing user inconvenience.
Innovation Solution
A data management method and apparatus that allows users to adjust memory space, move/copy data within non-volatile memory while maintaining the original format, and store data in extended regions or external storage without format alteration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If users copy or backup phonebook data to external storage, then memory space is secured for new entries, but data format changes causing user inconvenience
Solution Approach 1:
The patent implements a copying mechanism that creates backup copies of phonebook data in extended memory regions while preserving the original data format. The controller copies data between memory regions without format conversion, allowing users to recover deleted data by restoring from backups that maintain the original structure and format of phonebook entries.
2Device complexity
If phonebook memory region is limited in size, then memory management is simplified, but users must delete existing data to add new entries
Solution Approach 1:
The patent divides the phonebook memory into a basic region with fixed size and an extended region that can be dynamically adjusted. This segmentation allows the basic region to maintain simple management while the extended region provides additional capacity. Users can move data between regions and adjust the extended region size to balance between simplicity and adaptability.
Solution Approach 2:
The patent implements dynamic adjustment of the extended memory region size based on user needs and available space. The controller can expand or contract the extended region within certain limits, allowing the memory capacity to adapt to changing requirements while maintaining a manageable structure through the basic/extended region division.
3Loss of information
If users manually re-enter deleted phonebook data, then data recovery is possible, but time and effort are wasted
Solution Approach 1:
The patent performs preliminary backup actions by automatically creating copies of phonebook data in extended memory regions before deletion occurs. When users delete data from the basic region, the backup copies remain intact in the extended region, enabling immediate recovery without requiring users to manually re-enter any information, thus preventing both information loss and time waste.
4Productivity
If data is moved between memory regions, then memory utilization efficiency is improved, but data format may be altered
Solution Approach 1:
The patent ensures homogeneity of data format across different memory regions by implementing a unified data structure that is maintained during transfer operations. The controller copies data between the basic and extended regions without format conversion or alteration, ensuring that the data structure, field formats, and organizational hierarchy remain identical in both regions, thus maintaining data integrity while improving memory utilization.
Data Source
AI summary
A data management method and apparatus of a portable terminal improves memory utilization efficiency using a data move/copy function which allows moving or copying the user data preserved in the non-volatile memory region of the memory of a portable terminal. A data management method for a portable terminal includes selecting at least one user data item in response to a selection request. An extended region for backup of the user data item is checked in response to a backup request. Transfer data corresponding to the user data item is created. The transfer data is stored in the extended region as a backup of the user data item.
