Implementations described herein relate to memory section selection for a memory built-in self-test. A memory device may read a first set of bits stored in a test control mode register. The memory device may identify a test mode, for performing a memory built-in self-test, based on the first set of bits. The memory device may read a second set of bits stored in a section identifier mode register. The memory device may identify one or more memory sections of the memory device, for which the memory built-in self-test is to be performed, based on the second set of bits. The one or more memory sections may be a subset of a plurality of memory sections into which the memory device is divided. The memory device may perform the memory built-in self-test for the one or more memory sections of the memory device based on the test mode.
