MEMORY DEVICE AND METHOD FOR OPERATING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 18586174 titled 'MEMORY DEVICE AND METHOD FOR OPERATING THE SAME
The memory device described in the patent application includes a plurality of memory cells divided into a first group and a second group. The memory cells in the second group are programmed to a predefined logic state.
- The memory controller applies a reading voltage to selected memory cells in the first group during a reading operation.
- The reading voltage is also applied to the memory cells in the second group.
- If the logic state of a memory cell in the second group is different from the predefined logic state, a refresh operation is triggered.
- During the refresh operation, a recovery voltage higher than the reading voltage is applied to the memory cells in the first group.
- The memory cells in the first group are then reprogrammed to match the logic state assessed with the recovery voltage.
Potential Applications: - This technology can be used in various memory devices such as solid-state drives, embedded systems, and IoT devices. - It can improve the reliability and performance of memory storage systems.
Problems Solved: - Preventing data corruption in memory cells. - Enhancing the longevity of memory devices.

Original Abstract Submitted
A memory device can include a plurality of memory cells including a first group of memory cells and a second group of memory cells programmed to a predefined logic state. The plurality of memory cells includes a memory controller configured to apply a reading voltage to at least one selected memory cell of the first group during a reading operation, apply the reading voltage to the memory cells of the second group, and responsive to the logic state of at least one memory cell of the second group being assessed to be different from the predefined logic state perform a refresh operation of the memory cells of the first group by applying a recovery voltage higher than the reading voltage to assess the logic state thereof and reprogramming the memory cells of the first group to the logic state assessed with the recovery voltage.
