Solution Overview

Problem

Integrated circuit chips face limitations in increasing the number of settings without expanding the number of bits in selection codes or altering the design of decoders, which is a concern for adhering to standards like JEDEC and IEEE.

Innovation Solution

The implementation of a setting information storage circuit with multiple decoders and register sets, utilizing additional set signals to enable increased settings without modifying the selection code bits or decoder design, allowing for more items to be set without expanding the selection code transfer bus or changing the decoder design.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the number of bits in selection codes is increased to increase the number of settings, then the number of items that may be set increases, but the area of the selection code transfer bus must be increased and the design of the decoders must be changed

Engineering Contradiction:

Improvenumber of settingsVSAvoidarea of selection code transfer bus

Core Design Contradiction:

Adaptability or versatilityVSArea of stationary object

Solution Approach 1:

The patent divides the single set signal transfer line into multiple set signal transfer lines (first set signal transfer line and second set signal transfer line). Each decoder is assigned a specific set signal transfer line, allowing multiple decoders to operate independently with the same selection codes without requiring an increased bus area.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a new dimension by adding multiple set signal transfer lines instead of increasing the selection code bits. This allows the system to expand the number of settings by utilizing additional control signal dimensions rather than expanding the address space dimension.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

2Adaptability or versatility

If the number of bits in selection codes is increased to increase the number of settings, then the number of items that may be set increases, but the design of the decoders must be changed

Engineering Contradiction:

Improvenumber of settingsVSAvoiddesign of decoders

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the decoder system into multiple independent decoders (first decoder and second decoder), where each decoder is designed with the same fixed structure. This segmentation allows the system to handle more settings by adding parallel decoder units rather than increasing the complexity of individual decoders.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Each decoder is designed with a universal structure that can handle the same number of settings independently. The first decoder and second decoder both use identical design patterns, allowing the system to scale by replication rather than by increasing individual decoder complexity.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If additional set signals are used to increase the number of settings, then more items can be set without modifying selection code bits, but the number of set signal transfer lines increases

Engineering Contradiction:

Improvenumber of settingsVSAvoidnumber of set signal transfer lines

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the control signal distribution into multiple dedicated transfer lines, where each line serves a specific decoder. This segmentation allows the system to increase the number of settings by adding parallel control paths rather than complicating a single control path.

Inventive Principle:

Principle #1Segmentation
