Patent ID: 11880257
Assignee: YANGTZE MEMORY TECHNOLOGIES CO., LTD.
Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 0:
1. A method of peak power management (PPM) for multiple memory dies comprising a first memory die and a second memory die, wherein the first memory die comprises a first PPM circuit having a single first PPM contact pad, and the second memory die comprises a second PPM circuit having a single second PPM contact pad electrically connected with the single first PPM contact pad such that the single first PPM contact pad and the single second PPM contact pad share an electric potential, the method comprising:
starting a first peak power check (PPC) routine of the first memory die when the electric potential shared between the single first PPM contact pad and the single second PPM contact pad is at a first voltage level;
driving the electric potential shared between the single first PPM contact pad and the single second PPM contact pad to a second voltage level lower than the first voltage level at a first timing after starting the first PPC routine;
enabling the first memory die to wait for a first delay time period;
generating a pausing signal in the electric potential shared between the single first PPM contact pad and the single second PPM contact pad at a second timing after the first timing;
performing a first peak power operation of the first memory die; and
generating a resuming signal in the electric potential shared between the single first PPM contact pad and the single second PPM contact pad at a fifth timing after the first memory die has completed the first peak power operation.
