Abstract
Implementations described herein relate to performing a memory built-in self-test and indicating a status of the memory built-in self-test using a data mask inversion (DMI) bit. A memory device may read one or more bits, associated with a memory built-in self-test, that are stored in a mode register of the memory device. The memory device may identify a first DMI bit of the memory device that is associated with indicating a status of the memory built-in self-test and a second DMI bit of the memory device that is not associated with indicating the status of the memory built-in self-test. The memory device may set the first DMI bit to a first value based on the one or more bits indicating that the memory built-in self-test is enabled. The memory device may perform the memory built-in self-test based on setting the first DMI bit to the first value.
