A non-volatile memory with multiple memory dice manages simultaneous operations so as to not exceed a system power capacity. A load signal bus is pulled up with a strength proportional to the system power capacity. Each die has a driver to pull down the bus by an amount corresponding to its degree of power need as estimated by a state machine of the die. The bus therefore provides a load signal that serves as arbitration between the system power capacity and the cumulative loads of the individual dice. The load signal is therefore at a high state when the system power capacity is not exceeded; otherwise it is at a low state. When a die wishes to perform an operation and requests a certain amount of power, it drives the bus accordingly and its state machine either proceeds with the operation or not, depending on the load signal.
