Solution Overview

Problem

Existing memory systems face inefficiencies in the process of writing and managing dummy data, which is time-consuming and not directly managed by the memory device, affecting system throughput.

Innovation Solution

The memory device generates dummy data internally based on its own characteristics in response to a specific command, without receiving actual data from the controller, and manages this process to improve efficiency.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the memory device receives dummy data from the controller and writes it to the memory cell array, then the dummy data can be properly stored, but the transmission and filling time increases, reducing system throughput

Engineering Contradiction:
Improvedummy data storage reliabilityVSAvoidsystem throughput
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The memory device autonomously generates dummy data using its own internal resources (random number generator or adjacent page data) instead of receiving it from the external controller. This self-service approach eliminates the data transmission step and allows the memory device to independently complete the dummy data filling operation, thereby improving system throughput while ensuring reliable storage.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If the memory controller manages dummy data transmission and filling, then the data can be accurately provided, but the process becomes time-consuming and affects overall system efficiency

Engineering Contradiction:
Improvedummy data accuracyVSAvoiddummy data filling time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The memory device takes over the dummy data generation task from the memory controller, using its own internal resources to create and write dummy data. This transfers the time-consuming transmission and filling operations from the controller to the memory device itself, eliminating waiting time and improving overall system efficiency while maintaining data accuracy through the device's own generation capabilities.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The memory device performs dummy data generation as a preliminary action before actual data writing operations. By having the capability to generate dummy data internally and on-demand, the device prepares the memory cell array in advance for subsequent operations, reducing the time penalty associated with dummy data management and improving overall operational throughput.

Inventive Principle:
Principle #10Preliminary action
