Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If encryption strength is increased to improve data security, then data security is improved, but data processing rate and data transfer efficiency deteriorate
Solution Approach 1:
The patent applies dynamics by making the communication protocol selectable and changeable based on security requirements. The system can dynamically switch between different communication protocols (first communication protocol for normal operation, second communication protocol for enhanced security) rather than using a fixed encryption level. This allows the system to adjust security measures in real-time based on the specific access request, maintaining high data processing rates during normal operation while enabling strong security protection when needed.
2Reliability
If encryption strength is increased to improve data security, then data security is improved, but data transfer efficiency deteriorates
Solution Approach 1:
The patent applies dynamics by making the communication protocol selectable and changeable based on security requirements. The system can dynamically switch between different communication protocols (first communication protocol for normal operation, second communication protocol for enhanced security) rather than using a fixed encryption level. This allows the system to adjust security measures in real-time based on the specific access request, maintaining high data processing rates during normal operation while enabling strong security protection when needed.
3Productivity
If a single communication protocol is used for data transmission, then data transfer efficiency is maintained, but data security is compromised due to predictable operation patterns
Solution Approach 1:
The patent applies universality by equipping the memory control device with the capability to handle multiple communication protocols. The device can select from a first communication protocol for normal operations and a second communication protocol for enhanced security scenarios. This multi-functionality allows the system to adapt its communication method based on security requirements, preventing unauthorized access by making operation patterns unpredictable while still maintaining efficient data transfer when using the first protocol.

AI summary
A technique for improving data security is provided. To be specific, in a memory system including an information processing apparatus and a semiconductor memory device, the semiconductor memory device has an interface section that transmits, to the information processing apparatus, data read out from a memory core according to a plurality of communication protocols having different signal transmission/reception methods. Based on a switch command inputted from the information processing apparatus, a communication protocol selection section inputs, to the interface section, a selection signal for selecting a particular communication protocol from the plurality of communication protocols.
