Two levels of membership now exist: full membership and tools membership. Tools membership has lower cost, fewer benefits, and is available only to certain eligible companies. A table of cost and benefits is below.
Eligibility for tools membership
Tools membership is intended for companies that specialize in
providing software or hardware tools for development and testing,
including development and testing of SMIF protocols (like PMBus,
SMBus, SBS) and similar, related, or combined protocols (like I2C and IPMI).
A company that manufactures OEM or end-user products for production,
not just for development and testing, is not eligible for tools
membership, even if that company also provides tools.
Tools membership eligibility is determined by the SMIF board of
directors, whose decision is final.
