Memory Buffer Reuse for Programming Failure Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The performance of memory systems is degraded due to increased allocation of volatile memory for managing programming failures, leading to decreased efficiency in executing access commands.
Innovation Solution
Reusing a portion of volatile memory previously allocated for a different access command to manage data associated with programming failures, rather than dedicating a separate portion for this purpose.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate portion of volatile memory is allocated for managing programming failures, then the reliability of handling programming failures is improved, but the productivity of executing access commands deteriorates due to reduced available memory resources
Solution Approach 1:
The patent applies universality by enabling volatile memory to serve multiple functions: it is used both for executing access commands and for managing programming failure data. Instead of dedicating a separate portion of volatile memory solely for programming failures, the system reuses the same volatile memory resources for both purposes, thereby improving productivity while maintaining reliability through dynamic memory management.
Solution Approach 2:
The patent implements discarding and recovering by temporarily using volatile memory for programming failure data and then releasing it back for access command operations. The memory is dynamically allocated when needed for failure management and recovered/returned to the general pool for command execution, optimizing resource utilization and eliminating permanent allocation overhead.
2Reliability
If volatile memory is allocated for programming failure management, then the capability to handle programming exceptions is improved, but the volume of memory available for access commands decreases
Solution Approach 1:
The patent applies dynamics by making memory allocation dynamic rather than static. The volatile memory is dynamically allocated to programming failure management only when exceptions occur, and dynamically released when not needed. This dynamic approach ensures that memory volume for access commands is maximized during normal operation while still providing sufficient capacity for exception handling when required.
Solution Approach 2:
The same volatile memory resources are made universal, serving both access command execution and programming failure management functions. This multi-functionality eliminates the need for separate dedicated memory portions, thereby maintaining total available memory volume while providing exception handling capability.
3Ease of operation
If dedicated memory allocation is used for programming failures, then the ease of managing programming exceptions is improved, but the overall performance of the memory system deteriorates
Solution Approach 1:
The patent implements self-service by enabling the memory management system to automatically handle exception data using the same memory resources that handle normal operations. The system serves itself by reusing volatile memory for exception management without requiring separate dedicated structures, thereby maintaining ease of operation while avoiding performance degradation from reduced memory availability.
Solution Approach 2:
The memory system achieves universality by using a single volatile memory pool for both normal access commands and exception handling operations. This eliminates the performance penalty associated with dedicated memory allocation while maintaining operational simplicity through unified memory management.
Data Source
AI summary
Methods, systems, and devices for techniques for managing memory exception handling are described. A memory device may write first data associated with a first access command to a first portion of a buffer of a memory device. The memory device may determine a programming failure to write second data to a page of a first block of the memory device. In response to determining the programming failure, the memory device may perform an access operation associated with the first access command to vacate the first data from the first portion of the buffer. In response, the memory device may write the second data to the first portion of the buffer. The memory device may write the second data from the first portion of the buffer to a page of a second block of the memory device in response to writing the second data to the first portion of the buffer.
