Storage Device Spec Data for On-Demand Host Log Parsing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Host devices face challenges in efficiently managing and parsing data configuration information for memory devices, leading to inefficiencies and reliability issues due to the need for continuous updates of parsing information.
Innovation Solution
A host device and storage device system where the storage device stores spec data including parsing information for each log page identifier, allowing the host device to request and receive this data as needed, and encode context into binary data for human-readable analysis.

Engineering Contradiction Analysis
1Reliability
If the host device stores and periodically manages parsing information for each memory device, then data parsing capability is maintained, but management complexity and time consumption increase
Solution Approach 1:
The parsing information (spec data) is extracted from the host device and stored in the storage device itself. The host device only needs to request and receive this data when needed, rather than storing and managing it continuously. This extraction transfers the management burden from host to storage device, reducing host management time while maintaining parsing capability.
Solution Approach 2:
The storage device stores its own spec data and provides it to the host device upon request. This self-service approach allows the storage device to manage its own parsing information without requiring the host device to maintain updated parsing data for all devices, thereby reducing the host's management time and complexity.
2Manufacturing precision
If the host device continuously updates parsing information for memory devices, then data configuration accuracy is maintained, but operational efficiency decreases
Solution Approach 1:
Instead of continuous updates, the system uses periodic action where the host device requests spec data from the storage device only when needed (e.g., when initializing or when data parsing is required). The storage device maintains the spec data and provides it on-demand, achieving both accuracy and efficiency by eliminating unnecessary continuous management operations.
Solution Approach 2:
The storage device prepares and stores its spec data in advance within its own memory. This preliminary action ensures that when the host device needs parsing information, it is immediately available without requiring continuous updates or searches, thus maintaining accuracy while improving operational efficiency.
3Adaptability or versatility
If the host device manages parsing information for multiple storage devices, then comprehensive data parsing is achieved, but system complexity increases
Solution Approach 1:
Each storage device extracts and stores its own spec data independently. The host device simply requests the appropriate spec data from each storage device as needed, rather than maintaining a centralized database of parsing information for all devices. This extraction approach maintains comprehensive parsing coverage while significantly reducing host management complexity.
Solution Approach 2:
Each storage device independently manages and provides its own spec data to the host device. This self-service mechanism allows the host to work with multiple storage devices without increasing its own management complexity, as each device handles its own parsing information autonomously.

AI summary
A host device and a storage device are provided. A host device includes a controller configured to process log data related to a state of a first storage device by using first spec data, the first spec data including parsing information for each log page identifier; and a communication circuit, wherein the controller is further configured to: transmit a first request for requesting the first spec data to the first storage device through the communication circuit; receive the first spec data from the first storage device through the communication circuit in response to the first request; transmit a second request for requesting first log data to the first storage device through the communication circuit; and receive the first log data from the first storage device through the communication circuit in response to the second request and process the received first log data by using the first spec data.
