Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If write operations are performed continuously without temperature management, then write speed and productivity are improved, but heat generation increases and device reliability deteriorates
Solution Approach 1:
The patent implements periodic write operations by inserting idle periods between consecutive write tasks. The write timing controller schedules write operations to occur at specific time intervals, preventing continuous write operations that would generate excessive heat. This periodic action allows the memory device to cool down between writes, resolving the contradiction between maintaining high write speed and controlling temperature.
Solution Approach 2:
The patent performs preliminary temperature assessment before executing write operations. The write timing controller receives temperature information and determines the write timing in advance based on current temperature conditions. This preliminary action allows the system to adjust write scheduling proactively, preventing heat buildup before it becomes problematic while maintaining optimal write performance.
2Reliability
If write timing is adjusted based on temperature information, then temperature management and reliability are improved, but device complexity increases
Solution Approach 1:
The write timing controller performs multiple functions: it manages write scheduling, monitors temperature information, determines optimal write timing, and controls the write buffer. By consolidating these diverse functions into a single controller unit, the patent achieves effective temperature-based write management without proportionally increasing device complexity. The controller acts as a multi-functional hub that coordinates all write-related operations.
Solution Approach 2:
The patent merges the write timing control function with the existing write buffer and temperature information reception capabilities into an integrated write timing controller. This consolidation combines multiple previously separate functions into a unified control mechanism, achieving temperature-aware write management while minimizing the increase in overall device complexity through functional integration.
3Stability of the object's composition
If write data is stored in a write buffer before transfer, then write operation stability is improved, but write latency and time consumption increase
Solution Approach 1:
The patent implements dynamic control of the write buffer by the write timing controller, which adjusts buffer management based on real-time temperature conditions. When temperature is low, the controller enables faster buffer-to-memory transfer; when temperature is high, it extends buffer holding time to allow cooling. This dynamic adaptation optimizes the balance between write stability (requiring buffer storage) and write latency (requiring fast transfer).

AI summary
An electronic device includes a memory controller and a memory device. The memory controller that controls the memory device includes a write buffer to temporarily store write data received from a host, a write timing controller to receive temperature information indicating a temperature of the memory device and generate write timing information based on the temperature information, the write timing information indicating a write timing at which the write data is transferred to and stored in the memory device, and a write operation controller to control the write buffer and the memory device based on the write timing information such that the write data stored in the write buffer is transferred to and stored in the memory device.
