Recovery of memory from asynchronous power loss

A storage system comprising:

• at least one non-volatile memory device comprising multiple memory cells organized in physical pages;
• and
• a controller coupled to the at least one non-volatile memory device, wherein instructions are stored in the storage system, wherein the instructions, when executed by the controller, cause the controller to perform operations, comprising:
• in response to a detected asynchronous power loss (APL) at the storage system, determine a number of ones stored in a first physical page of memory cells;
• and
• determine whether to write dummy data to the first physical page using the determined number of ones in the first physical page.

A method implemented by controller of a storage system comprising at least one non-volatile memory device comprising multiple memory cells organized in physical pages, the method comprising:

• detecting an asynchronous power loss (APL) at the storage system;
• in response to the detected APL, determining a number of ones stored in a first physical page of memory cells of the storage system;
• and
• determining whether to write dummy data to the first physical page using the determined number of ones in the first physical page.

At least one non-transitory device-readable storage medium comprising instructions that, when executed by a controller of a storage system, cause the controller to perform operations comprising:

• detecting an asynchronous power loss (APL) at the storage system;
• in response to the detected APL, determining a number of ones stored in a first physical page of memory cells of the storage system;
• and
• determining whether to write dummy data to the first physical page using the determined number of ones in the first physical page.
