Title:
PEAK POWER MANAGEMENT FOR MULTI-DIE OPERATIONS
Document Type and Number:
WIPO Patent Application WO/2022/165786
Kind Code:
A1
Abstract:
A method of peak power management (PPM) is provided for two NAND memory dies. Each NAND memory die comprises a PPM circuit having a PPM contact pad held at an electric potential common between the two NAND memory dies. The method includes the following steps: detecting the electric potential during a first peak power check (PPC) routine for the first NAND memory die; driving the electric potential to a second voltage level if the detected electric potential is at a first voltage level higher than the second voltage level; generating a pausing signal in the electric potential to pause a second PPC routine for the second NAND memory die if no pausing signal is detected; and generating a resuming signal in the electric potential to resume the second PPC routine for the second NAND memory die after the first NAND memory die completes a first peak power operation.
