Abstract
A system includes a memory component to, upon completion of second pass programming in response to a multi-pass programming command, write flag bits within a group of memory cells programmed by the multi-pass programming command A processing device, operatively coupled to the memory component, is to perform multi-pass programming of the group of memory cells in association with a logical address. Upon receipt of a read request, the processing device is to determine that a second logical address within the read request does not match the logical address associated with data stored at a physical address of the group of memory cells. The processing device is further to determine a number of first values within the plurality of flag bits, and in response to the number of first values not satisfying a threshold criterion, report, to a host computing device, an uncorrectable data error.
