The  '''Advanced Host Controller Interface''' ('''AHCI''') is a technical standard defined by [[Intel]] that specifies the [[Hardware register|register-level interface]] of [[Serial ATA]] (SATA) [[host controller]]s in a non-implementation-specific manner in its [[Intel chips|motherboard chipsets]].<ref name=":0" />

The specification describes a system memory structure for computer hardware vendors to exchange data between host system [[computer memory|memory]] and attached [[computer storage device|storage devices]]. AHCI gives software developers and hardware designers a standard method for detecting, configuring, and programming SATA/AHCI adapters. AHCI is separate from the SATA 3&nbsp;Gbit/s standard, although it exposes SATA's advanced capabilities (such as [[hot swapping]] and [[Native Command Queuing|native command queuing]]) such that host systems can utilize them. For modern [[Solid-state drive|solid state drives]], the interface has been superseded by [[NVM Express|NVMe]].<ref>{{Cite web|title=NVMe vs. SATA: Which SSD Technology Is Faster?|url=https://www.howtogeek.com/657972/nvme-vs.-sata-which-ssd-technology-is-faster/|access-date=2020-10-10|website=www.howtogeek.com}}</ref>

The current version of the specification is 1.3.1.
