MULTI-DIE MEMORY DEVICE WITH PEAK CURRENT REDUCTION

Abstract:

A memory device including a substrate including a substrate contact pad. The memory device includes a first memory die including a first power supply contact pad electrically coupled to the substrate contact pad and a first power supply circuit on the first memory die. The first memory die further includes a first electrostatic discharge (ESD) power clamp contact pad electrically coupled to the substrate contact pad and a first ESD power clamp circuit on the first memory die. The memory device further includes a second memory die including a second power supply contact pad electrically coupled to the substrate contact pad and a second power supply circuit on the second memory die and a second ESD power clamp contact pad electrically coupled to a second ESD power clamp circuit on the second memory die, wherein the second ESD power clamp contact pad is electrically disconnected from the substrate contact.
