NOTICE
JEDEC standards and publications contain material that has been prepared, reviewed, and approved
through the JEDEC Board of Directors level and subsequently reviewed and approved by the JEDEC
legal counsel.
JEDEC standards and publications are designed to serve the public interest through eliminating
misunderstandings between manufacturers and purchasers, facilitating interchangeability and
improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the
proper product for use by those other than JEDEC members, whether the standard is to be used either
domestically or internationally.
JEDEC standards and publications are adopted without regard to whether or not their adoption may
involve patents or articles, materials, or processes. By such action JEDEC does not assume any liability to
any patent owner, nor does it assume any obligation whatever to parties adopting the JEDEC standards or
publications.
The information included in JEDEC standards and publications represents a sound approach to product
specification and application, principally from the solid state device manufacturer viewpoint. Within the
JEDEC organization there are procedures whereby a JEDEC standard or publication may be further
processed and ultimately become an ANSI standard.
No claims to be in conformance with this standard may be made unless all requirements stated in the
standard are met.
Inquiries, comments, and suggestions relative to the content of this JEDEC standard or publication should
be addressed to JEDEC at the address below, or refer to www.jedec.org under Standards and Documents
