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.

Multi-die memory device with peak current reduction

A memory device including a memory die including an internally-powered thermometer to determine a first measured operating temperature value of the memory die; detect the first measured operating temperature value satisfies one of a first condition or a second condition; and generate a first signal indicating an out-of-range operating temperature of the memory die in response to one of the first condition or the second condition being satisfied by the first measured operating temperature value. The memory die also including an externally-powered thermometer to: determine a second measured operating temperature value of the memory die; detect the second measured operating temperature value satisfies one of the first condition or the second condition; and generate a second signal indicating the out-of-range operating temperature of the memory die in response to one of the first condition or the second condition being satisfied by the second measured operating temperature value.
