Mixed-Data Memory Reads Using Encoded Status Indicators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Memory devices face inefficiencies in processing read commands for mixed data with different memory statuses, leading to increased latency and resource consumption due to separate data transfer requests for each status.
Innovation Solution
The memory device encodes data with status indicators and provides a single data transfer request for read commands involving mixed data, allowing the hardware component to determine appropriate responses based on these indicators.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate data transfer requests are generated for each logical block with different memory statuses, then accurate data transfer is achieved, but processing time increases and resources are consumed
Solution Approach 1:
The patent combines multiple separate data transfer requests into a single unified request by encoding status indicators directly into the data structure. Instead of generating individual requests for each logical block with different memory statuses (valid, invalid, reserved), the system merges these into one request that carries encoded status information for each block, thereby reducing processing time while maintaining accurate data transfer.
Solution Approach 2:
The patent creates a universal data transfer request structure that can handle multiple memory statuses within a single request. The encoded data structure serves multiple functions: it identifies valid data, marks invalid data, and indicates reserved blocks, all within one unified request format that can be processed by a single data transfer operation.
2Reliability
If separate data transfer requests are generated for each logical block with different memory statuses, then data accuracy is maintained, but resource consumption increases
Solution Approach 1:
The patent merges multiple resource-intensive data transfer requests into a single request by encoding status information within the data structure. This consolidation reduces the number of separate processing operations required, thereby decreasing CPU usage, memory access operations, and overall resource consumption while maintaining the ability to accurately handle different memory statuses.
Solution Approach 2:
The patent changes the parameter representation by encoding multiple status indicators into a compact data structure. Instead of treating each memory status as a separate control parameter requiring individual request handling, the system encodes these statuses within the data payload itself, allowing a single request to convey information about multiple logical blocks with different statuses.
3Productivity
If a single data transfer request is used for mixed data, then processing efficiency improves, but complexity in determining appropriate responses increases
Solution Approach 1:
The patent applies preliminary action by encoding all necessary status information into the data structure before the data transfer request is processed. The status indicators are prepared and embedded in advance, allowing the receiving system to determine appropriate responses without requiring complex real-time analysis. This pre-encoding of status information simplifies the response determination process despite using a single unified request.
Data Source
AI summary
In some implementations, a memory device may receive, from a host device, a read command indicating data and one or more logical block addresses to be read from a memory of the memory device. The memory device may obtain a memory unit from the memory based on the read command. The memory device may determine status information associated with the one or more logical block addresses based on information indicated by the memory unit. The memory device may generate a single data transfer request associated with the one or more logical block addresses, where the single data transfer request indicates status indicators associated with respective logical block addresses of the one or more logical block addresses. The memory device may provide, to the host device, one or more responses to the read command, where the one or more responses are based on the status indicators.
