Abstract
Memory devices and systems with configurable die powerup delay, and associated methods, are disclosed herein. In one embodiment, a memory system includes two or more memory dies. At least one memory die has a powerup group terminal and powerup group detect circuitry. The powerup group detect circuitry is configured to detect a powerup group assigned to the at least one memory die. The at least one memory die is configured to delay its powerup operation by a time delay corresponding to the powerup group to which it is assigned. In this manner, powerup operations of the two or more memory dies can be staggered to reduce peak current demand of the memory system.
