Abstract: A determination is made that a memory device of a memory sub-system is to be transitioned to a sleep mode. A command is initiated to cause a standby circuit associated with the memory device to enter into a low power mode while a power supply of the memory sub-system is maintained in a powered state. In the low power mode, a reference voltage is supplied to a voltage regulator of the standby circuit to supply a standby current level to the memory device during the sleep mode.

Abstract: A memory device includes a memory array comprising a plurality of wordlines and a regulator circuit selectively coupled to the plurality of wordlines, wherein the regulator circuit is configured to perform a detection routine to sample a load current from a selected wordline of the plurality of wordlines and generate a measured output voltage, wherein the measured output voltage modulates with respect to the load current. The memory device further includes a comparator circuit coupled to the regulator circuit, wherein the comparator circuit is configured to generate a comparison result based on a difference between the measured output voltage and a reference voltage and a local media controller coupled to the comparator circuit, wherein the local media controller is configured to identify a presence of a defect on the selected wordline in response to the comparison result satisfying a threshold condition.
