MEMORY DEVICE AND OPERATING METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 18309637 titled 'MEMORY DEVICE AND OPERATING METHOD THEREOF
Simplified Explanation
The memory device described in the patent application performs a detrap operation on a selected memory block when the number of program/erase cycles of the block reaches a certain threshold. This operation involves applying a heating current to a heating layer that is thermally coupled to the channel of each string in the selected memory block.
- The memory device performs a detrap operation on a memory block after a predetermined number of program/erase cycles.
- A heating current is applied to a heating layer that is thermally coupled to the channels of the memory block's strings during the detrap operation.

Original Abstract Submitted
A memory device performs a detrap operation on a selected memory block when the number of program/erase cycles of the selected memory block equals or exceeds a predetermined set number. A circuit included in the memory device applies a heating current to a heating layer, thermally coupled to the channel of each of the plurality of strings included in the selected memory block in the detrap operation.
