MEMORY DEVICE PERFORMING REFRESH OPERATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 18156126 titled 'MEMORY DEVICE PERFORMING REFRESH OPERATION
Simplified Explanation
The disclosed patent application describes a memory device that includes a memory bank with multiple memory cells, and control logic that manages data input/output operations for these cells. The control logic measures a refresh count, which represents the number of times an event causing a leakage current occurs in the memory cells. Based on this refresh count, the control logic performs a partial refresh operation on the memory bank.
- The memory device includes a memory bank with multiple memory cells.
- Control logic is responsible for managing data input/output operations for the memory cells.
- The control logic measures a refresh count associated with the occurrence of events causing a leakage current in the memory cells.
- The refresh count is measured partially with respect to the memory bank.
- Based on the refresh count, the control logic performs a partial refresh operation on the memory bank.
Potential Applications:
- This memory device can be used in various electronic devices that require efficient memory management, such as computers, smartphones, and tablets.
- It can be particularly useful in devices that have limited power resources, as the partial refresh operation helps optimize power consumption.
Problems Solved:
- Leakage current in memory cells can lead to data loss or corruption. The control logic in this memory device helps mitigate this issue by performing a refresh operation based on the measured refresh count.
- The partial refresh operation reduces the overall power consumption of the memory device, addressing the problem of power efficiency in memory management.
Benefits:
- Improved reliability and data integrity by addressing the issue of leakage current in memory cells.
- Optimized power consumption, leading to increased battery life in portable electronic devices.
- Enhanced memory management efficiency, resulting in improved overall performance of electronic devices.
Original Abstract Submitted
Disclosed is a memory device which includes a memory bank including a plurality of memory cells, and control logic controlling a data input/output operation for the plurality of memory cells. The control logic partially measures a refresh count, which is associated with the number of times of occurrence of at least one event causing a leakage current in the plurality of memory cells, with respect to the memory bank, and partially performs a refresh operation on the memory bank based on the refresh count.
