Memory Command Response Packing for Bandwidth-Efficient Developer Data
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The transmission of developer commands between host systems and memory storage devices occupies bandwidth, leading to decreased access performance and increased product development burden due to additional workflows required for processing these commands.
Innovation Solution
A command responding method that generates a response message with both first type response data reflecting the execution result of the operation command and second type response data unrelated to the execution result, improving message transmission efficiency between the host system and memory storage device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If developer commands are transmitted between host system and memory storage device, then customized functions can be performed, but transmission bandwidth is occupied and access performance decays
Solution Approach 1:
The patent merges the response to developer commands with the existing command response mechanism. By incorporating command response data and developer command response data into a single response message structure, the system eliminates separate transmission channels for developer commands, thereby consolidating bandwidth usage and maintaining access performance while enabling customized functions.
Solution Approach 2:
The response message structure is designed to serve multiple functions simultaneously: it carries both the command response data and the developer command response data. This universal response mechanism allows the system to handle both standard commands and customized developer commands through a single unified protocol, avoiding additional bandwidth consumption.
2Adaptability or versatility
If additional workflows are configured to process developer commands, then customized functions can be executed, but product development burden increases
Solution Approach 1:
The memory storage device autonomously processes developer commands and generates response data without requiring complex external workflows. The device self-manages the command processing, data formatting, and response transmission, thereby reducing the development burden on the host system while maintaining the ability to execute customized functions.
Solution Approach 2:
The patent introduces a standardized response message structure as an intermediary between the host system and memory storage device. This intermediary framework simplifies the interaction by providing a predetermined template for command responses, eliminating the need for complex custom workflows and reducing product development complexity while enabling versatile customized functions.
Data Source
AI summary
A command responding method, a memory storage device, and a memory control circuit unit are disclosed. The command responding method includes the following steps. An operation command is received from a host system. A response message is generated according to the operation command, in which the response message carries a first type response data and a second type response data, the first type response data reflects an execution result of the operation command, and the second type response data is not related to the execution result of the operation command. The response message is sent to the host system in response to the operation command.
