Program continuation strategies after memory device power loss

A method comprising:

• detecting, by a processing device, a power up event of a memory device;
• responsive to detecting the power up event, selecting, by the processing device, an open block of the memory device, wherein the open block comprises a set of pages;
• analyzing, by the processing device, the set of pages to obtain at least one of:
• at least one charge loss metric indicative of charge loss associated with a set of programmed pages of the set of pages, the set of programmed pages comprising at least one of:
• an oldest written page of the open block, or at least one first sample page associated with at least one respective individual charge loss metric;
• or
• at least one charge gain metric indicative of charge gain associated with a set of erased pages of the set of pages, the set of erased pages comprising at least one of:
• an initial erased page of the open block, or at least one second sample page associated with at least one respective individual charge gain metric;
• determining, by the processing device based on at least one of the at least one charge loss metric or the at least one charge gain metric, whether the open block is valid for programming;
• and
• responsive to determining that the open block is invalid for programming, abandoning, by the processing device, the open block.

A non-transitory computer-readable storage medium comprising instructions that, when executed by a processing device, cause the processing device to perform operations comprising:

• detecting a power up event of a memory device;
• responsive to detecting the power up event, selecting an open block of the memory device, wherein the open block comprises a set of pages, and wherein the set of pages comprises at least one of:
• a set of programmed pages comprising at least one of:
• an oldest written page of the open block, or at least one first sample page associated with at least one respective individual charge loss metric;
• or
• a set of erased pages comprising at least one of:
• an initial erased page of the open block, or at least one second sample page associated with at least one respective individual charge gain metric;
• analyzing the set of pages to obtain at least one of:
• at least one charge loss metric indicative of charge loss associated with the set of programmed pages or at least one charge gain metric indicative of charge gain associated with the set of erased pages;
• determining, based on at least one of the at least one charge loss metric or the at least one charge gain metric, whether the open block is valid for programming;
• and
• responsive to determining that the open block is valid for programming, keeping the open block open for programming.
