Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If individual commands are used for programming dummy data to each open page, then programming completeness is improved, but device complexity and operation time increase

Engineering Contradiction:

Improveprogramming completenessVSAvoidcommand management complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple individual programming commands into a single unified command that simultaneously programs dummy data to all open pages within a partial memory block. This merging approach maintains programming completeness while significantly reducing command management complexity and operation time.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention creates a universal programming command structure that can handle multiple open pages simultaneously, making the command system more versatile. This multi-functional command can adapt to different numbers of open pages without requiring separate individual commands for each page.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If individual commands are used for programming dummy data to each open page, then programming completeness is improved, but operation time increases

Engineering Contradiction:

Improveprogramming completenessVSAvoiddummy data programming time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent merges sequential programming operations into a single parallel operation, where one unified command programs dummy data to all open pages simultaneously. This eliminates the time required to process multiple individual commands sequentially, significantly reducing total programming time while ensuring all pages are properly programmed.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The invention enables continuous programming action across all open pages within a partial memory block by using a single command that operates on all pages without interruption. This continuous operation eliminates the start-stop nature of sequential command execution, optimizing programming efficiency.

Inventive Principle:

Principle #20Continuity of useful action

3Reliability

If multiple commands are used for dummy data programming, then programming coverage is improved, but ease of operation deteriorates

Engineering Contradiction:

Improveprogramming coverageVSAvoidcommand execution simplicity

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent combines multiple programming commands into one unified command structure that covers all open pages. This merging simplifies the operation for users and controllers, as they only need to issue a single command rather than managing multiple individual commands, while still achieving complete programming coverage across all pages.

Inventive Principle:

Principle #5Merging (Combining)

4Manufacturing precision

If traditional programming operations are used for partial memory blocks, then manufacturing process precision is maintained, but productivity decreases

Engineering Contradiction:

Improveprogramming accuracyVSAvoidmemory block processing efficiency

Core Design Contradiction:

Solution Approach 1:

The invention merges multiple programming operations into a single optimized process that maintains the precision required for proper dummy data programming while dramatically improving productivity. The unified command structure ensures accurate programming of all open pages without the overhead of multiple separate operations.

Inventive Principle:

Principle #5Merging (Combining)
