Dynamic Refresh Rate Control - A simplified explanation of the abstract
This abstract first appeared for US patent application 18488656 titled 'Dynamic Refresh Rate Control
Simplified Explanation
The abstract describes a patent application for a memory controller in an integrated circuit that adjusts the refresh rate of DRAMs based on the rate of change of temperature.
- Memory controller in an integrated circuit
- Generates refreshes for DRAMs based on a refresh rate
- Includes temperature sensors
- Determines rate of change of temperature
- If rate is above threshold, generates refreshes at specified rate by DRAMs
- If rate is below threshold, generates refreshes at reduced rate
Potential Applications
This technology could be applied in various electronic devices that use DRAMs, such as computers, smartphones, and servers, to optimize memory performance based on temperature changes.
Problems Solved
1. Overheating of DRAMs leading to memory errors or failures. 2. Inefficient memory refresh rates that waste power and reduce performance.
Benefits
1. Improved memory performance and reliability. 2. Energy efficiency by adjusting refresh rates based on temperature. 3. Extended lifespan of DRAMs by preventing overheating.
Potential Commercial Applications
"Dynamic Memory Refresh Rate Adjustment Technology for Enhanced Performance and Reliability"
Possible Prior Art
There may be existing technologies that adjust memory refresh rates based on temperature changes, but the specific method described in this patent application may be novel.
Unanswered Questions
How does this technology impact the overall power consumption of the integrated circuit?
The abstract does not provide details on how the memory controller's adjustment of refresh rates based on temperature affects the power consumption of the integrated circuit.
Are there any limitations to the rate at which the refresh rate can be adjusted?
The abstract does not mention any constraints or limitations on how quickly or frequently the refresh rate can be adjusted based on temperature changes.
Original Abstract Submitted
In an embodiment, a memory controller in an integrated circuit may generate refreshes for one or more DRAMs coupled to the integrated circuit according to a refresh rate. The integrated circuit may include one or more temperature sensors. A rate of change of the temperature may be determined from the temperature sensors. If the rate is greater than a threshold, the memory controller may generate refreshes according to a refresh rate specified by the DRAMs. If the rate is less than the threshold, the memory controller may generate refreshes at a reduced refresh rate.
