Serial Port Memory Technology


The SPMT Consortium is a coalition of companies involved in designing and manufacturing mobile devices, integrated circuits, and semiconductor IP. The organization developed the SPMT specification, which is a SerDes memory interface primarily for commodity DRAM and mobile markets.
The specification is ideal for data intensive, media-rich functionality like video, GPS, internet access, email, multimedia, and music.

History

The SPMT Consortium was founded in 2009 by ARM Holdings, Hynix Semiconductor, Inc., LG Electronics, Samsung Electronics Co., Ltd. and Silicon Image, Inc. The Consortium is managed by SPMT, LLC, the entity responsible for licensing the SPMT memory interface specification. SPMT is a memory specification for dynamic random access memory that is based on SerDes rather than a standard parallel interface.
