Abstract
A method of peak power management (PPM) for a memory chip with multiple memory dies is provided, where each of the multiple memory dies includes a PPM circuit having a PPM contact pad and PPM contact pads of the multiple memory dies are electrically connected. The PPM method includes the following steps: switching on a pull-down driver of the PPM circuit on a selected memory die of the memory chip; verifying a PPM enablement signal regulated by a pull-down current flowing through the pull-down driver; and performing a peak power operation on the selected memory die when the PPM enablement signal indicates that a total current of the memory chip is less than a maximum total current allowed for the memory chip.
