Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing storage devices with wireless communication functions face challenges in suppressing noise from being mixed into data during writing operations, particularly when handling audio and image data, due to interference from wireless signals and power consumption issues.
Innovation Solution
A storage device configuration that includes a control circuit and a statistical processing unit to determine the type of data being written, allowing it to prioritize data writing over wireless communication and manage wireless transmission accordingly, using a combination of interface, memory, and wireless circuits to prevent noise interference and optimize power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless communication is performed simultaneously with data writing, then communication continuity is maintained, but noise interferes with data integrity
Solution Approach 1:
The control circuit determines in advance whether write data is audio data before writing begins. When audio data is detected, the control circuit proactively stops wireless communication before the writing operation starts, preventing noise interference from affecting data integrity. This preliminary detection and preventive action resolve the contradiction by ensuring data integrity is maintained without completely sacrificing communication continuity, as communication can resume after writing completes.
2Reliability
If wireless communication is stopped during data writing, then noise interference is reduced, but power consumption increases due to extended operation time
Solution Approach 1:
Instead of stopping wireless communication for all data writing operations, the control circuit applies partial action by selectively stopping communication only when audio data is being written. For non-audio data, wireless communication continues normally. This selective approach reduces power consumption compared to a complete stop, while still protecting audio data integrity from noise interference.
3Productivity
If wireless communication is continuously performed, then communication functionality is maintained, but noise is mixed into audio data during writing
Solution Approach 1:
The control circuit continuously monitors the type of data being written through feedback from the data classification process. When audio data writing is detected, the control circuit provides feedback to stop wireless communication. After writing completes, the system detects the end of writing operation and provides feedback to restart communication. This feedback mechanism ensures communication functionality is maintained whenever possible while preventing noise interference during critical audio data writing operations.

AI summary
According to one embodiment, a storage device includes a non-volatile memory, an interface circuit, a first control circuit, a wireless transmitting and receiving circuit, and a second control circuit. The interface circuit is electrically connected to the host device and is capable of communicating the host device. The first control circuit performs control of writing write data received from the host device via the interface circuit into the non-volatile memory. The wireless transmitting and receiving circuit is capable of wirelessly communicating with a wireless device. The second control circuit determines whether or not the write data include a predetermined type of data based on measurement data of the write data, and stops wireless communication performed by the wireless transmitting and receiving circuit if it is determined that the write data include the predetermined type of data.
