The SPMT Consortium is a coalition of companies involved in designing and manufacturing mobile devices, integrated circuits, and semiconductor IP.^[1] The organization developed the SPMT specification, which is a SerDes memory interface primarily for commodity DRAM and mobile markets. ^[2] The specification is ideal for data intensive, media-rich, functionality like video, GPS, internet access, email, multimedia, and music.^[1]^[3]

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.^[4] SPMT is the first memory specification for dynamic random access memory (DRAM) that is based on SerDes rather than the standard parallel interface. <3rd party citation needed here for industry-first claim>^[1]

Technology Summary

SPMT Technology alt text — SPMT Functional Blocks

a. 20 signaling pins for 6GB/s performance
b. Simultaneous Read/Write
c. Low energy per bit – (4 – 5 pJ/bit effective)
d. Self-clocking
e. Low EMI
f. High noise rejection
g. Standard DRAM commands
h. Burst lengths of 16, 32, and 64 bytes
i. Low voltage differential signaling

Members

The SPMT Consortium is divided into three levels of membership: Promoters (Founders), Contributors, and Members.

Promoters (Founders): Define, implement and promote Serial Port Memory Technology for broad market adoption as an industry standard.

Contributors: Work in cooperation with the promoters and participate in the definition of future SPMT specifications.

Members: Have access to the latest version of the SPMT specification and the rights to create innovative products that implement the technology. The SPMT Consortium assesses an annual fee from all members to help fund the marketing, administration and licensing activities of the Consortium.
