Abstract
The disclosure provides a memory device and a control method thereof. The control method of the memory device includes: receiving an erase command and performing an erasing operation on a memory block; when a plurality of suspend events occurs during the erasing operation, counting a resume number of the resume events respectively corresponding to a plurality of suspend events or a suspend number of the suspend events; and during the erasing operation, performing a first soft-program operation on the memory block when the resume number or the suspend number is greater than or equal to a threshold value.
Claims18
A control method of a memory device, comprising:
- receiving an erase command and performing an erasing operation on a memory block;
- counting a resume number of a plurality of resume events respectively corresponding to a plurality of suspend events or a suspend number of the suspend events when the suspend events occur during the erasing operation;
- performing a first soft-program operation on the memory block during the erasing operation when the resume number or the suspend number is greater than or equal to a threshold value;
- and
- resetting the resume number or the suspend number after the first soft-program operation.
A memory device, comprising:
- a memory block;
- and
- a logic circuit, coupled to the memory block, configured to:
- receive an erase command and perform an erasing operation on a memory block;
- count a resume number of a plurality of resume events respectively corresponding to a plurality of suspend events or a suspend number of the suspend events when the suspend events occur during the erasing operation;
- and
- perform a first soft-program operation on the memory block during the erasing operation when the resume number or the suspend number is greater than or equal to a threshold value,
- wherein the logic circuit comprises a counter, the counter is configured to:
- reset the resume number or the suspend number after the first soft-program operation.
