JEDEC Publishes Registered Outline for 1.8-inch Slim Solid State Drives

Organization Taking the Lead on SSD Standards

ARLINGTON, Va., USA - MAY 18, 2009 - JEDEC Solid State Technology Association, the global leader
in standards development for the microelectronics industry, today announced the publication of
registered outline MO-297 for 1.8" Slim Solid State Drives. These types of SSDs have a range of
applications in consumer products, including netbooks and laptops. As the first industry standard to
target SSDs, MO-297 is indicative of JEDEC’s leadership in setting comprehensive SSD standards. The
document is available for free download at, as part of JEDEC Publication 95: Registered and Standard Outlines for Solid State and Related Products.

MO-297 defines the dimensions, layout and connector position for 54mm x 39mm solid state drives
with a standard SATA connector. Adopting a standard form factor for these types of solid state drives will
enable interoperability throughout the supply chain, benefiting drive manufacturers, product designers
and consumers. Conforming to a single standard will simplify the product design process, shortening
time to market and facilitating a reduction in costs.

The development of SSD standards involves various JEDEC committees as well as numerous
external standards organizations. The MO-297 registered outline correlates directly with SFF Committee
specification SFF-8156, and also references the Serial ATA International Organization’s (SATA-IO)
Revision 2.6 Specification for connector dimension and tolerance.

"MO-297 is the first document to standardize a physical outline for a solid state drive. Adoption of
this standard has the potential to deliver significant benefits for the industry by creating a single outline
for storage suppliers and systems manufacturers to use and reference," said Jim Leidy, Business
Development Manager for Tyco Electronics and Chairman of the JEDEC Task Group behind the effort. He added, "Consumers will also have the benefit of vendor choice and ease of replacement, since drives
adhering to the standard will be interchangeable."

Mian Quddus, JEDEC Board of Directors’ Chairman said, "I applaud the JC-11 Committee on
publication of MO-297, which is an important first step in JEDEC’s delivering a comprehensive set of
standards for solid state drives."

In addition to the efforts of JC-11 and other JEDEC committees, JEDEC’s JC-64.8 Subcommittee for
Solid State Drives continues to lead the industry push to develop critical SSD specifications in a timely
manner. All interested parties are encouraged to contact the JEDEC office at 703-907-7560 to become
involved with SSD standards development.


JEDEC is the leading developer of standards for the solid-state industry. Over 3,500 participants, appointed by
some 300 companies work together in 50 JEDEC committees to meet the needs of every segment of the industry,
manufacturers and consumers alike. The publications and standards that they generate are accepted throughout
the world. All JEDEC standards are available online, at no charge. For more information, visit
