Problem

Current semiconductor memory devices face challenges in reducing power consumption and increasing processing speed, particularly in write operations, due to the need for input/output circuit usage.

Innovation Solution

A memory device and system that includes a memory cell array, a data pattern providing unit, and a write circuit capable of writing predefined data patterns without an input/output circuit when a write command is received, by using a pattern write command and address signal to internally generate and write data patterns to memory regions, reducing data transmission and power consumption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If data transmission is used for write operations, then data can be written to memory, but power consumption increases and processing speed decreases

Engineering Contradiction:
Improvepower consumptionVSAvoidprocessing speed
Core Design Contradiction:
Use of energy by moving objectVSProductivity

Solution Approach 1:

The memory device generates and writes data patterns autonomously using an internal data pattern generating unit without requiring external data transmission through the data bus. This self-service mechanism eliminates the need for input/output circuits during write operations, thereby reducing power consumption and increasing processing speed while maintaining correct data writing functionality.

Inventive Principle:
Principle #25Self-service

2Productivity

If input/output circuit is used for write operations, then data can be written to memory, but device complexity increases

Engineering Contradiction:
Improvewrite operation efficiencyVSAvoidinput/output circuit complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The invention extracts and eliminates the input/output circuit from the data writing path by introducing an internal data pattern generating unit that produces data patterns directly within the memory device. This extraction removes the complex external data transmission pathway while simplifying the overall device architecture and maintaining efficient write operation capability.

Inventive Principle:
Principle #2Taking out (Extraction)

3Reliability

If data transmission between memory controller and device is performed, then data can be written, but power consumption increases

Engineering Contradiction:
Improvedata writing reliabilityVSAvoidpower consumption
Core Design Contradiction:
ReliabilityVSUse of energy by moving object

Solution Approach 1:

The memory device performs self-service by generating data patterns internally through the data pattern generating unit without requiring data transmission from the memory controller. This eliminates the energy-consuming data transmission process while maintaining reliable data writing through the internally generated patterns, achieving both reliability and energy efficiency.

Inventive Principle:
Principle #25Self-service
