Methods, systems, and devices for targeted test fail injection are described. A memory device may include self-test circuitry configured to test one or more memory cells of a memory array. The self-test circuitry may be configured to store one or more addresses to fail during a test of the memory array based on an indication from a mode register of the memory device. The self-test circuitry may be configured to fail the stored one or more addresses regardless of the outcome of the test at the one or more memory addresses. For example, when an accessed address matches a stored address during test, the self-test circuitry may generate an indication that the accessed address has failed one or more tests of the self-test procedure. Based on the self-test circuitry failing the stored addresses, a test of the memory array may be validated.
