NAND detect program completion (NDPC) with power off charge loss calibration in a memory sub-system

A method comprising:

• responsive to detecting a power-up event, performing, by a processing device, a first read strobe on a first set of a plurality of memory cells addressable by a first wordline;
• determining a value of a conductivity metric reflecting conductive states of one or more bitlines connected to the first set of the plurality of memory cells addressable by the first wordline;
• determining, based on the value of the conductivity metric, a read level offset value for a second wordline, wherein the second wordline is adjacent to the first wordline;
• performing, using the read level offset value for the second wordline, a second read strobe on the second wordline;
• determining, based on the value of the conductivity metric, a quality criterion;
• and
• responsive to determining that a value of a quality metric produced by the second read strobe satisfies the quality criterion, indicating that a programming operation performed on the second wordline was completed before a power off event.

A computer-readable non-transitory storage medium comprising executable instructions that, when executed by a controller managing a memory device comprising a plurality of memory cells, cause the controller to:

• responsive to detecting a power-up event, perform a first read strobe on a first set of a plurality of memory cells addressable by a first wordline;
• determine a value of a conductivity metric reflecting conductive states of one or more bitlines connected to the first set of the plurality of memory cells addressable by the first wordline;
• determine, based on the value of the conductivity metric, a read level offset value for a second wordline, wherein the second wordline is adjacent to the first wordline;
• perform, using the read level offset value for the second wordline, a second read strobe on the second wordline;
• determine, based on the value of the conductivity metric, a quality criterion;
• and
• responsive to determining that a value of a quality metric produced by the second read strobe satisfies the quality criterion, indicate that a programming operation performed on the second wordline was completed before a power off event.
