Power management in memory

Abstract

The present disclosure includes apparatuses and methods related to power management in memory. Memory devices with multiple input/output ports may have the ports separately managed to transfer data from the various to a host or other components of the module based on certain power management signaling or constraints. For example, a memory device with multiple ports may be managed to transfer data to a host from one set of ports in response to power management (or other) signaling, and the device may be managed to transfer other data to another memory device in response to different power management (or other signaling). Power management may be done onboard a memory module with or without direction from a host. Power management may be performed by a dedicated integrated circuit. Data may be transferred from or between different classes of memory devices, using different ports, based on power management, e.g., criteria.
