Solution Overview
Problem
Existing semiconductor storage devices lack efficient methods for writing and reading data using sensor information, leading to suboptimal storage and retrieval processes.
Innovation Solution
The method involves a storage device with a spatial sensor that updates a logical storage area management table based on spatial information to determine the logical location for data storage and retrieval, allowing data to be written and read efficiently without storing spatial information with the data, thereby reducing data size and enhancing performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If spatial information is stored together with data, then data location can be tracked, but data size increases and storage efficiency decreases
Solution Approach 1:
The patent extracts spatial information from the data storage process by using separate sensors (GPS, accelerometer, gyroscope) to capture spatial data independently. This extracted spatial information is then used to determine logical storage areas without being embedded in the actual data, thereby reducing data size while maintaining spatial tracking capability.
Solution Approach 2:
The patent introduces a logical storage area management table as an intermediary between physical storage and data. This table maps spatial information to logical storage areas, allowing the system to track data locations without storing spatial information directly with the data, thus maintaining efficiency while enabling spatial awareness.
2Quantity of substance
If data is written to any available physical storage area, then storage capacity is maximized, but retrieval efficiency decreases
Solution Approach 1:
The patent performs preliminary action by determining the logical storage area based on spatial information before actually writing data to physical storage. The logical storage area management table is updated in advance with the mapping between spatial information and target storage areas, enabling efficient retrieval without searching through all available space.
Solution Approach 2:
The patent segments the storage system into logical storage areas that correspond to different spatial regions. This segmentation allows data to be organized by location, so when retrieval is needed, the system can quickly identify the relevant logical storage area based on spatial information rather than searching the entire storage capacity.
3Productivity
If spatial information is received and processed for each data operation, then storage efficiency improves, but operational complexity increases
Solution Approach 1:
The patent makes the logical storage area management table universal by using it for both write operations (determining target storage areas) and read operations (identifying storage areas for retrieval). This single data structure handles multiple functions, reducing operational complexity while maintaining storage efficiency.
Solution Approach 2:
The system uses the sensor information to automatically determine logical storage areas without requiring manual intervention or complex algorithms. The logical storage area management table self-updates with spatial information, enabling the system to serve itself in managing data locations efficiently.

AI summary
In a method of writing data in a storage device, a data write request is received from a host device. Spatial information is received from a spatial sensor included in the storage device based on the data write request. A logical storage area management table is updated based on the data write request and the spatial information such that target data to be stored is written into a target storage area corresponding to the spatial information among a plurality of logical storage areas. A program command and the target data are transmitted to a nonvolatile memory such that the target data is programmed into a physical storage area in the nonvolatile memory corresponding to the target storage area.
