A method includes receiving, by control logic of a memory device, a copyback clear command from a processing device; causing, in response to the copyback clear command, a page buffer to perform a dual-strobe read operation on first memory cells configured as single-level cells, the dual-strobe read operation including a soft strobe at a first threshold voltage and a hard strobe at a second threshold voltage that are sensed between threshold voltage distributions of the first memory cells; causing the page buffer to determine a number of one bit values within the threshold voltage distributions detected in a threshold voltage range between the first/second threshold voltages; and causing, in response to the number of one bit values not satisfying a threshold criterion, a copyback of data in the first memory cells to second memory cells configured as high-level cells without intervention from the processing device.
