Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing serial memory devices face challenges in efficiently transmitting data values and error detection codes over multiple serial data links, where data units and error detection codes are not synchronously transmitted, leading to potential errors and inefficiencies in data transfer.
Innovation Solution
A system and method where data units and error detection codes are transmitted on different serial links, allowing for simultaneous transmission of data values and error detection codes, enabling error detection and correction during read and write operations, with configurations that include multiple serial links for address, data, and error detection codes, ensuring accurate data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If data units and error detection codes are transmitted on the same serial link, then device complexity is reduced, but data transfer reliability deteriorates due to potential errors without timely detection
Solution Approach 1:
The patent segments the transmission medium into multiple independent serial links, with dedicated links for data units and separate links for error detection codes. This segmentation allows simultaneous transmission of data and error detection information without interference, resolving the contradiction between simplified configuration and reliable error detection.
Solution Approach 2:
The patent introduces separate error detection code links as intermediary channels that carry error detection information independently from data units. This intermediary approach enables the system to maintain simple device configuration while ensuring reliable error detection through dedicated transmission paths.
2Reliability
If data units and error detection codes are transmitted simultaneously on separate serial links, then data transfer reliability is improved, but device complexity increases due to multiple link configurations
Solution Approach 1:
The patent implements universal serial link interfaces that can handle both data units and error detection codes through a standardized multi-link configuration. This multi-functionality approach allows the same interface architecture to support reliable simultaneous transmission without proportionally increasing device complexity, as the links follow uniform design principles.
3Device complexity
If error detection codes are transmitted after data units on the same link, then device complexity is minimized, but data transfer efficiency deteriorates due to sequential transmission
Solution Approach 1:
The patent transitions from sequential transmission on a single link to parallel transmission across multiple links, effectively adding a spatial dimension to the transmission process. This dimensional change enables simultaneous transmission of data units and error detection codes, dramatically improving data transfer efficiency without complicating the fundamental transmission configuration.

AI summary
A serial interface device includes multiple serial link connections that receive at least address values and at least one error detection code (EDC) on different serial link connections, the EDC generated from at least the address values, the serial link connections for the address values and EDC operated separately from one another; and multiple output serial links, at least a first one of the output serial links outputting data values read from memory locations corresponding to the address values, and at least a second one of the output serial links different from and operated separately from the first one outputting EDC values generated for the data values read from the memory locations.
