1. A peak power management (PPM) system for a storage system with multiple memory dies, comprising:
a PPM circuit on each of the multiple memory dies, the PPM circuit comprising a first pull driver, a second pull driver, and a PPM contact pad connected between the first pull driver and the second pull driver, wherein:
PPM contact pads of the multiple memory dies are electrically connected with each other; and
the PPM system is configured to manage peak power operations based on an electric potential of the PPM contact pads, wherein the electric potential of the PPM contact pads is determined according to a first pull current flowing through a certain first pull driver of a certain PPM circuit and the first pull current is a sum of second pull currents flowing through second pull drivers of PPM circuits in the PPM system.
