Abstract
Described apparatuses and methods relate to self-refresh arbitration. In a memory system with multiple memory components, an arbiter is configured to manage the occurrence of self-refresh operations. In aspects, the arbiter can receive one or more self-refresh request signals from at least one memory controller for authorization to command one or more memory components to enter a self-refresh mode. Upon receiving the one or more self-refresh request signals, the arbiter, based on a predetermined configuration, can transmit one or more self-refresh enable signals to the at least one memory controller with authorization to command the one or more memory components to enter the self-refresh mode. The configuration can ensure that fewer than all memory components simultaneously enter the self-refresh mode. In so doing, memory components can perform self-refresh operations without exceeding an instantaneous power threshold. The arbiter can be included in, for instance, a Compute Express Link™ (CXL™) memory module.
