Abstract: Exemplary methods, apparatuses, and systems include a performance throttling manager for controlling performance levels of a memory subsystem using input voltages. The performance throttling manager monitors input voltages to a memory device to determine a current input voltage value, while the memory device is operating at a first performance level. The performance throttling manager detects that the current input voltage value satisfies a threshold voltage value. The performance throttling manager selects a second performance level that is lower than the first performance level and throttles the performance of the memory device in response to detecting that the current input voltage value satisfies a threshold voltage value.
