Scalable Coherent Interface [SEP] inception
for the technology starting in 1996. A series of workshops were held through 1999.
After the first 1992 edition, follow-on projects defined shared data formats in 1993, a version using low-voltage differential signaling in 1996, and a memory interface known as Ramlink later in 1996.
In January 1998, the SLDRAM corporation was formed to hold patents on an attempt to define a new memory interface that was related to another working group called SerialExpress or Local Area Memory Port.
However, by early 1999 the
Scalable Coherent Interface
The Scalable Coherent Interface or Scalable Coherent Interconnect (SCI), is a high-speed interconnect standard for shared memory multiprocessing and message passing. The goal was to scale well, provide system-wide memory coherence and a simple interface; i.e. a standard to replace existing buses in multiprocessor systems with one with no inherent scalability and performance limitations.
The IEEE Std 1596-1992, IEEE Standard for Scalable Coherent Interface (SCI) was approved by the IEEE standards board on March 19, 1992. It
