A system and method for preserving block experiencing wordline failure in memory devices. An example method includes performing, by a processor, a write operation to program data to a set of memory cells addressable by a first wordline of a plurality of wordlines of a block of a memory device; determining that a program fault occurred during the write operation; determining a number of wordlines referenced by a program fault data structure that are associated with the block; and responsive to determining that the number of wordlines fails to satisfy a threshold criterion, releasing a second wordline of the plurality of wordlines to be available for write operations.
