Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing memory systems face challenges in efficiently managing and controlling host memory access, particularly in handling commands and data transfers between host systems and memory devices, which can lead to inefficiencies and increased complexity.
Innovation Solution
The implementation of a memory device system that receives commands from a host, processes them, and executes data transfers independently, using a standardized interface to manage command sequences and data buffers, allowing memory devices to control the timing, sequence, and priority of data transfers without requiring host intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the host system manages and maintains the state of memory devices through hardware control, then command execution control is centralized, but device complexity and host resource allocation increase
Solution Approach 1:
The memory device is equipped with a state machine that autonomously manages command execution without requiring continuous host intervention. The device independently tracks its own state, manages data buffers, and controls transfer operations, enabling self-service operation that reduces host system complexity while maintaining centralized control benefits
2Productivity
If the host controller builds and manages all command sequences, then command execution is centralized, but host system resource allocation and management overhead increase
Solution Approach 1:
The command execution functionality is segmented between the host controller and the memory device state machine. The host initiates commands and provides high-level control, while the memory device's state machine handles detailed command sequencing, state tracking, and data buffer management. This segmentation improves productivity by enabling parallel operations while reducing the host's management burden through automated device-side control
3Productivity
If the memory device executes commands autonomously with internal state management, then data transfer control is improved, but device internal complexity increases
Solution Approach 1:
The state machine is designed as a universal control component that handles multiple command types and execution scenarios through a unified state management architecture. By creating a multi-functional state machine that can manage various operations (data transfers, command sequencing, buffer management) through a single integrated mechanism, the patent reduces overall device complexity compared to having separate control logic for each function, while maintaining high command execution efficiency
