Memory and storage pool interfaces

Abstract

Examples herein relate to a system capable of coupling to a remote memory pool, the system comprising: a memory controller and an interface to a connection, the interface coupled to the memory controller. In some examples, the interface is to translate a format of a memory access request to a format accepted by the memory controller and the memory controller is to provide the translated memory access request in a format accepted by a media. In some examples, a controller is to measure a number of addressable regions that are least accessed and cause at least one of the least accessed regions to be evicted to a local or remote memory device with relatively higher latency. In some examples, a remote access manager is to: determine if a region of addressable memory associated with a memory address for an access request is stored in the memory; based on the region of addressable memory associated with the memory address being stored in the memory, determine if a sub-region of addressable memory associated with the memory address is available for access from the memory, wherein the sub-region comprises less than an entirety of the region; and based on the sub-region of addressable memory being available for access from the memory, provide a physical address for use to access data from the sub-region in the memory and copy the data to the cache.
