Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Memory devices face challenges in supporting multiple memory densities without complex data-path designs, as existing technologies require different data-paths for each memory density, leading to inefficiencies in data alignment and transfer.
Innovation Solution
A data interleaving module that interleaves data received from a bus among modules according to selected memory densities, allowing for seamless data alignment and transfer to a register without the need for a specific data-path for each density, enabling support for various memory densities while maintaining data alignment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If different data-paths are used for each memory density, then data alignment is maintained, but device complexity increases
Solution Approach 1:
A single data-path is designed to support multiple memory densities (SLC and various MLC configurations) through configurable parameters rather than requiring separate dedicated data-paths for each density type. The same physical infrastructure handles different data widths and alignment requirements by adjusting operational parameters.
Solution Approach 2:
The data-path incorporates dynamic configuration capabilities that allow it to adapt its behavior based on the selected memory density mode. Parameters such as data width, alignment offsets, and transfer timing can be dynamically adjusted to match the requirements of the currently active memory density configuration.
2Device complexity
If a single data-path supports multiple memory densities, then device complexity is reduced, but data alignment becomes difficult to maintain
Solution Approach 1:
The system maintains data alignment across multiple memory densities by dynamically changing operational parameters including data width, byte offsets, and transfer timing. Configuration registers allow software to set appropriate parameters for each memory density mode, ensuring proper alignment without requiring hardware-specific data-paths.
Solution Approach 2:
Configuration registers and control logic act as intermediaries between the host system and the physical data-path, translating high-level memory density selections into specific parameter settings that maintain proper data alignment. This intermediary layer abstracts the complexity of alignment requirements from the host while preserving precise control over data transfer characteristics.
3Adaptability or versatility
If memory devices support multiple data densities, then adaptability increases, but data-path design becomes overly complicated
Solution Approach 1:
The data-path is designed as a universal infrastructure that can operate with different memory densities (supporting both SLC and multiple MLC configurations) through parameter configuration rather than requiring separate dedicated paths for each density type.
Solution Approach 2:
The memory system is segmented into configurable functional blocks with independent parameter settings, allowing each segment to be optimized for its specific memory density mode while sharing common infrastructure. This modular approach with configurable parameters reduces overall complexity compared to fully dedicated paths.
