Technology summary

# 20 signaling pins for 6 GB/s performance # Simultaneous Read/Write # Low energy per bit – (4–5 pJ/bit effective) # Self-clocking # Low EMI # High noise rejection # Standard DRAM commands # Burst lengths of 16, 32, and 64 bytes # 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 Standard may refer to: Symbols * Colours, standards and guidons, kinds of military signs * Standard (emblem), a type of a large symbol or emblem used for identification Norms, conventions or requirements * Standard (metrology), an object ...

. * 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.

Timeline of events

* May 18, 2009 - SPMT Consortium announced. * July 21, 2009 - SPMT President appointed. * August 17, 2009 - ARM joins SPMT as Promoter. * August 31, 2009 - SPMT releases abridged specification. * October 1, 2009 - SPMT releases new technology specification.
