Abstract
A memory device comprising an array of memory cells organized into a set of sub-blocks and a set of wordlines. Control logic is operatively coupled with the array of memory cells, the control logic to perform operations including: receiving a program command from a processing device, the program command including information indicative of a physical address associated with a retired wordline of the set of wordlines; in response to detecting the information within the program command, generating dummy data that is one of pseudo-random data, all one values, or all zero values; and causing the dummy data to be programmed to memory cells of multiple sub-blocks of the set of sub-blocks that are selectively connected to the retired wordline.
