Solution Overview

Problem

Existing memory devices experience decreased performance and increased operation time due to frequent temperature measurements during internal operations, which can lead to failed operations when internal temperatures become excessively high, especially when the interval between operations is short.

Innovation Solution

The memory device employs a temperature information controller to generate a pre-generated temperature code during a set period, allowing it to omit temperature measurements for internal operations commanded within that period and perform operations based on the pre-generated code, thereby improving operation speed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If temperature measurements are performed frequently during internal operations, then temperature control reliability is improved, but operation speed deteriorates and operation time increases

Engineering Contradiction:

Improvetemperature control reliabilityVSAvoidoperation speed

Core Design Contradiction:

ReliabilityVSSpeed

Solution Approach 1:

The patent measures temperature in advance before a series of internal operations and stores the temperature information. This preliminary temperature measurement allows subsequent operations to proceed without repeated temperature measurements, thus improving operation speed while maintaining temperature control reliability through the use of the pre-acquired temperature data.

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If temperature measurements are performed frequently during internal operations, then temperature monitoring accuracy is improved, but operation time increases

Engineering Contradiction:

Improvetemperature monitoring accuracyVSAvoidoperation time

Core Design Contradiction:

Measurement precisionVSDuration of action of moving object

Solution Approach 1:

The patent performs temperature measurement before executing multiple internal operations and stores the temperature information for reuse. This preliminary action ensures accurate temperature monitoring is achieved once, while subsequent operations benefit from this data without incurring additional measurement time, thus reducing total operation time while maintaining monitoring accuracy.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The stored temperature information from a single measurement is utilized across multiple subsequent internal operations. This multi-functional use of the temperature data allows accurate temperature monitoring to serve multiple operations simultaneously, reducing the need for repeated measurements and thereby decreasing total operation time.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Reliability

If temperature measurements are performed frequently during internal operations, then temperature control reliability is improved, but productivity deteriorates

Engineering Contradiction:

Improvetemperature control reliabilityVSAvoidoperation throughput

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The patent measures temperature in advance and stores it for use during multiple internal operations. This preliminary temperature acquisition ensures reliable temperature control information is available, while subsequent operations can proceed without interruption for temperature measurements, thereby improving operation throughput and productivity.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

By storing temperature information and using it across multiple continuous internal operations, the patent maintains continuous useful action without interruption for repeated temperature measurements. This continuous operation mode improves productivity while the stored temperature data ensures reliable temperature control throughout the operation sequence.

Inventive Principle:

Principle #20Continuity of useful action
