SELF-REFRESH STATE WITH DECREASED POWER CONSUMPTION - A simplified explanation of the abstract
This abstract first appeared for US patent application 17808818 titled 'SELF-REFRESH STATE WITH DECREASED POWER CONSUMPTION
Simplified Explanation
Methods, systems, and devices are disclosed for reducing power consumption in a memory system by implementing a self-refresh state. Here is a simplified explanation of the abstract:
- The memory system enters a self-refresh state to refresh a set of memory cells.
- Initially, the memory system performs a first set of refresh operations on the memory cells at a certain rate.
- While in the self-refresh state, the memory system determines whether to decrease the rate of refresh operations based on whether each memory cell has been refreshed at the initial rate.
- If the determination is made to decrease the rate, the memory system executes a second set of refresh operations at a slower rate while still in the self-refresh state.
Potential applications of this technology:
- Memory systems in electronic devices such as smartphones, tablets, and laptops.
- Embedded memory systems in IoT devices, wearables, and other small form factor devices.
- Server and data center memory systems.
Problems solved by this technology:
- Power consumption reduction: By implementing a self-refresh state and adjusting the rate of refresh operations, the memory system can reduce power consumption.
- Memory cell degradation prevention: Regular refresh operations help prevent data loss and maintain the integrity of stored information.
Benefits of this technology:
- Improved energy efficiency: The ability to decrease the rate of refresh operations allows for better power management and reduced energy consumption.
- Extended battery life: By reducing power consumption, devices utilizing this technology can experience longer battery life.
- Enhanced memory reliability: Regular refresh operations at appropriate rates help prevent memory cell degradation and improve overall system reliability.
Original Abstract Submitted
Methods, systems, and devices for a self-refresh state with decreased power consumption are described. A memory system may enter a self-refresh state to refresh a set of rows of memory cells at the memory system. Based on entering the self-refresh state, the memory system may execute a first set of refresh operations on the rows of memory cells according to a first rate. Additionally, the memory system may determine, while in the self-refresh state, whether to decrease the rate for executing the refresh operations to a second rate based on whether each of the rows of memory cells is refreshed according to the first rate. In cases that the memory system determines to decrease the rate for executing the refresh operations, the memory system may execute a set of second refresh operations on the rows of memory cells according to the second, slower, rate while in the self-refresh state.
