Asynch

Operations

Widely adopted SCSI command set and architecture model

Well-known high-performance protocol also used in USB 3.0, SAS, etc.

Enables Asynchronous Operation and Command Queuing

Utilize MIPI M-PHY and UniPro standards for the Physical and Link layers

Designed for mobile

High speed interface

Higher energy efficiency

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

Configured with UFS card when purchased

Consumer adds or upgrades functionality - later

Flexible Deployment Options

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

Premium mobile device & price

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
