Memory Command Queuing for Parallel Data Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional memory systems experience significant idle time and performance inefficiencies when transferring data across multiple memory components, as they wait for other components to complete data loading and transfer operations, leading to increased latency and reduced system performance.
Innovation Solution
A transfer controller component is employed to facilitate data transfers between memory components and a processor, generating a transfer map to reorder data in a predefined sequence, allowing each memory component to service commands independently and transfer data without waiting for others to complete their operations, using a queue system to manage commands and buffer data for proper ordering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If memory components wait for other components to complete data loading and transfer operations before transferring their data, then data transfer order is maintained, but idle time increases and system performance decreases
Solution Approach 1:
The patent divides the data transfer process into independent segments for each memory component. Each component can transfer its loaded data independently without waiting for other components, eliminating the sequential waiting pattern. The transfer controller manages multiple parallel transfer operations, allowing each memory component to operate autonomously once data is loaded.
Solution Approach 2:
The system performs preliminary data loading into buffers before the actual transfer to the host processor. Data is pre-loaded into memory component buffers and staged for transfer, allowing the loading and transfer operations to be decoupled. This preliminary buffering enables memory components to prepare data in advance without blocking other operations.
2Reliability
If memory components transfer data in a predefined order to satisfy host processor expectations, then data integrity is maintained, but transfer efficiency decreases due to waiting for other components
Solution Approach 1:
The transfer controller acts as an intermediary between memory components and the host processor. It receives data from multiple memory components simultaneously, reorders or buffers the data as needed, and then presents it to the host processor in the correct predefined order. This mediator approach allows parallel data reception while maintaining sequential output integrity.
Solution Approach 2:
The patent introduces a temporal dimension to data transfer by implementing buffering and staging areas. Data can be transferred across multiple dimensions - spatially from different memory components in parallel, and temporally through buffer stages before final host processor delivery. This multi-dimensional approach decouples the parallel loading efficiency from the sequential transfer requirement.
3Productivity
If memory components service commands independently without waiting for others, then idle time is reduced, but data ordering becomes complex
Solution Approach 1:
The patent merges the control functions of multiple memory components into a single transfer controller. Instead of each component having independent control logic for ordering and coordination, the transfer controller consolidates these functions. This centralization simplifies individual component design while enabling complex coordinated behavior through the unified controller that manages all transfers.

AI summary
Systems and/or methods that facilitate transferring data between a processor component and memory components are presented. A transfer controller component facilitates controlling data transfers in part by receiving respective subsets of data from respective memory components and arranging the respective subsets of data based in part on a desired predefined data order. The processor component generates a transfer map that includes information to facilitate arranging data in a predefined order. The processor component generates respective subsets of commands that are provided to queue components in respective memory components to retrieve desired data from the respective memory components. Each memory component services the commands in its queue component in an independent and parallel manner, and transfers the data retrieved from memory to the transfer controller component, which can arrange the received data in a predefined order for transfer to the processor component.
