� UFS Upgrade Card only� Lower initial price - yet feature rich capable

Flexible Deployment OptionsFlexible Deployment Options

� UFS Embedded only� Feature & performance rich ”out of the box”

� Premium mobile device & price

� Lower initial price - yet feature rich capable

� Configured with UFS card when purchased

� Consumer adds or upgrades functionality - later

27

� 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

Low Risk Host Deployment StrategyLow Risk Host Deployment Strategy

� Hosts can support SD & UFS interface for initial market� Serial (UFS) and parallel (SD) interfaces require separate pins� Hosts can support super set socket for SD and UFS� UFS card pins will be designed to not interfere with SD connector pins for the

“super set socket” � Future “dedicated” UFS connector designs reclaim unused pin-out space for

adding second data lane
