7. Flexible Deployment Options
 UFS Embedded only
 Feature & performance rich ”out of the box”
 Premium mobile device & price
 UFS Upgrade Card only
 Lower initial price - yet feature rich capable
 Configured with UFS card when purchased
 Consumer adds or upgrades functionality - later
 Hybrid model
 Sufficient embedded UFS for initial applications
 UFS upgrade card capable for additional functionality
 Both UGC and new feature rich applications
 Together - deliver seamless, high IOPS performance

 The UFS Standard is developed in JEDEC JC64 committee, incorporating MIPI
M-PHY and UniPro, and INCITS T10 SCSI specification standards
 UFS device electrical specification
 UFS device mechanical specification
 UFS host controller interface specification
 The Universal Flash Storage Association (UFSA) focuses on ecosystem
enablement and compliance certification

9. The Universal Flash Storage Association (UFSA) was founded
in 2010 as an open Trade Association to promote widespread industry adoption
and acceptance of the UFS standard.
Primary Missions:
 UFS technology promotion
 UFS infrastructure enablement
 Product compliance and UFS logo certification management
 Technical input into JEDEC for future specifications
Current Board Members:
 Samsung, Micron, SK Hynix, Agilent, Phison & Silicon Motion
