Measurement of representative charge loss in a block to determine charge loss state

A method comprising:

• detecting an occurrence of a triggering event;
• determining respective levels of charge loss associated with a first representative wordline of a block of a memory device and with a second representative wordline of the block of the memory device;
• determining whether a difference between the respective levels of charge loss satisfies a threshold criterion;
• and
• responsive to determining that the difference between the respective levels of charge loss satisfies the threshold criterion, determining that the block is in a uniform charge loss state.

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

• receiving a request to perform a read operation on a block of a memory device;
• accessing an entry associated with the block in a data store, the entry comprising an indication of whether the block is in a uniform charge loss state, wherein the indication is based on whether a difference between respective levels of charge loss associated with a first representative wordline of a block of a memory device and with a second representative wordline of the block of the memory device satisfies a threshold criterion;
• and
• responsive to the entry indicating that the block is in a uniform charge loss state, performing the read operation on the block using a uniform charge loss compensation technique.
