Abstract
An asynchronous power loss (APL) event is detected at a memory device. An APL affected page is identified in the memory device in response to detecting the APL event. A dummy write operation is performed to write dummy data to the APL affected page using an enhanced programming sequence with a reduced pulse count to reduce program disturb errors on neighboring pages.
Claims20
A system comprising:
- a memory device comprising at least one memory block comprising multiple pages;
- and
- a processing device, operatively coupled with the memory device, to perform operations comprising:
- detecting an asynchronous power loss (APL) event at the memory device;
- in response to detecting the APL event,
- identifying a page from the multiple pages that is affected by the APL event;
- and
- performing a dummy write operation on the page, the dummy write operation comprising writing dummy data to the page using an enhanced programming sequence with a reduced pulse count relative to a default pulse count used in normal write operations.

A method comprising:
- detecting an asynchronous power loss (APL) event at a memory device comprising multiple pages;
- in response to detecting the APL event,
- identifying an APL affected page from the multiple pages;
- and
- performing a dummy write operation on the page, the dummy write operation comprising writing dummy data to the APL affected page using an enhanced programming sequence with a reduced pulse count relative to a default pulse count used in normal write operations.

A computer-readable storage medium comprising instructions that, when executed by a processing device, configure the processing device to perform operations comprising:
- detecting an asynchronous power loss (APL) event at a memory device that comprises multiple pages;
- in response to detecting the APL event,
- identifying a page from the multiple pages that is affected by the APL event;
- and
- performing a dummy write operation on the page, the dummy write operation comprising writing dummy data to the page using an enhanced programming sequence with a reduced pulse count relative to a default pulse count used in normal write operations.
