Title:
ANALOG PEAK POWER MANAGEMENT FOR MULTI-DIE OPERATIONS
Document Type and Number:
WIPO Patent Application WO/2022/099493
Kind Code:
A1
Abstract:
Methods of peak power management (PPM) for a memory chip having multiple memory dies are disclosed. Each memory die includes a first PPM circuit and a second PPM circuit. First PPM circuits of the multiple memory dies are electrically connected to form a first PPM group. Similarly, second PPM circuits are electrically connected to form a second PPM group. Peak power operations can be managed by switching on a first pull-down driver of the first PPM circuit on a selected memory die when a first PPM enablement signal of the first PPM group is zero; waiting for a first delay period; switching on a second pull-down driver of the second PPM circuit on the selected memory die when a second PPM enablement signal of the second PPM group is zero. The first and second PPM enablement signals depend on the current flowing through each pull-down driver in the first and second PPM groups.
