Solution Overview

Problem

Storage media testing is time-consuming due to the long time required for data output during the comparison of stored and original data, which increases the overall testing time.

Innovation Solution

A storage medium with a processing module and cell array that receives test data, stores it, and compares it with verify data to generate a report, allowing for efficient data access verification through write and comparison commands.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If the storage medium stores data and then outputs the data for comparison, then the data verification can be performed, but the testing time is increased due to the long data output time

Engineering Contradiction:

Improvedata verification accuracyVSAvoidtesting time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The patent combines the data output operation and the comparison operation into a single integrated process. The processing module simultaneously performs data output and comparison with verify data, eliminating the sequential execution delay. This merging of operations allows the storage medium to verify data integrity without the time penalty of separate output and comparison steps.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent enables continuous verification operations by maintaining the comparison function active during data output. Rather than outputting all data first and then comparing, the system continuously compares data as it is being output, ensuring uninterrupted verification workflow and reducing total testing time.

Inventive Principle:

Principle #20Continuity of useful action

2Measurement precision

If the storage medium uses traditional read-then-compare method, then data accuracy can be verified, but the testing efficiency is reduced

Engineering Contradiction:

Improvedata accuracy verificationVSAvoidtesting efficiency

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The storage medium incorporates a built-in comparison function within its processing module, allowing it to perform self-verification of stored data. The system compares output data with stored verify data internally without requiring external testing equipment, enabling faster verification and improving overall testing efficiency while maintaining accuracy.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The patent pre-stores verify data in the storage medium alongside or separate from test data. This preliminary preparation of reference data allows for immediate comparison when test data is output, eliminating the need for external reference data preparation and accelerating the verification process.

Inventive Principle:

Principle #10Preliminary action
