Methods and systems for latency optimized ATS usage are disclosed. Aspects of one method may include communicating a memory access request using an untranslated address and also an address translation request using the same untranslated address, where the translation request may be sent without waiting for a result of the memory access request. The memory access request and the address translation request may be made in either order. A translation agent may be used to translate the untranslated address, and the translated address may be communicated to the device that made the memory access request. The translated address may also be used to make the memory access. Accordingly, by communicating the translated address without having to wait for completion of the memory access, or vice versa, the requesting device may reduce latency for memory accesses when using untranslated addresses.
