Memory Device Multi-Command Status Response Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional memory device communications protocols lack the ability for the memory device to initiate status updates, leading to performance issues and potential data inconsistencies when commands take longer than expected, as they rely on host requests for status inquiries.
Innovation Solution
Implementing a multi-command status response mechanism that allows the memory device to provide status information for multiple commands proactively, reducing communication overhead and enabling more flexible communication without altering existing protocols.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the memory device relies on host requests for status inquiries, then communication protocol simplicity is maintained, but communication efficiency deteriorates and performance issues occur when commands take longer than expected
Solution Approach 1:
The memory device proactively provides status information for multiple commands before the host requests it. When processing a second command, the device includes status information for a first command in the response, enabling the host to receive timely updates without waiting for separate inquiry requests.
Solution Approach 2:
The multi-command status response mechanism establishes a feedback loop where the memory device automatically returns status information for previously issued commands when processing new commands. This creates continuous status reporting without requiring additional host-initiated queries.
2Loss of time
If the memory device provides status updates proactively, then performance monitoring timeliness is improved, but communication overhead increases
Solution Approach 1:
The patent combines multiple status responses into a single communication transaction. When the host requests status for a second command, the memory device merges the status information for both the first and second commands into one response message, reducing the number of separate communication exchanges.
Solution Approach 2:
The status response mechanism serves multiple functions simultaneously: it answers the host's inquiry about the second command while also providing proactive status updates for the first command. This multi-functionality reduces the need for separate communication transactions.
3Productivity
If separate host inquiries are required for each command status, then communication protocol simplicity is maintained, but productivity deteriorates due to increased communication rounds
Solution Approach 1:
The memory device prepares and includes status information for completed or in-progress commands in advance within the response to current host requests. This preliminary inclusion of status data eliminates the need for subsequent separate inquiry requests from the host.
Data Source
AI summary
Devices and techniques for generating a response to a host with a memory device are provided. A first command from a host can be executed. A status for the first command can he determined. An inquiry from the host about a second command can be received after execution of the first command has begun. A response can be made to the inquiry that includes information about the second command and the status for the first command.
