1 Universal Flash Storage - Ultimatum of next generation Storage - Las Vegas, USA 7 th of Jan, 2011 Sung H. Lee Samsung Electronics Co. LTD Flash CES 2011

2 What are in your backpack?

3 What are in your backpack? So many digital devices.

4 What is inside? So many different types of storage

5 What do we do with?

6 Multimedia Enjoying multimedia < < SD Full HD Full HD + 3D 1.4 GB / 60 min 3.7 GB / 60 min ~ x2 [H.264 encoded]

7 Enjoying gizmos Multimedia Smartphone Perform mance Feature phone MP3, Pictures HD contents, Full browsing Applications and more Basic Call & SMS

8 Enjoying Apps Multimedia Smartphone Applications 24% of US adults use apps on their cellphones OVER 250K apps on Apple s & 80K on Android [Source: LA Times, Sept. 14, 2010]

9 Enjoying the flow of info Multimedia Smartphone Applications Mobile Web browsing Mobile web browsers usages [Source: Aug. 03, 2010

10 Enjoying freedom of multi-task HOST Device Multimedia PROCESS A MP3 PLAY PROCESS B Download Data Applications Traditional emmc Read Write APP STOP Internal Write (Merge) Smartphone Mobile Web browsing Multi-tasking Low latency is must for seamless user experience MB/s (Write)

11 What do we do with? Multimedia Smartphone Applications Mobile Web browsing Multi-tasking and MORE!!

12 What do we come up with?

13 What are we planning to do? SSD High performance Serial interface Command queuing

14 What are we planning to do? Mobile usages friendly Flash memory oriented Low power e-mmc

15 What are we planning to do? SSD e-mmc

16 What are we planning to do? SSD e-mmc UFS

17 What is UFS? Universal Flash Storage Embedded & Removable devices 300MB/s with future scalability Employ a multi-device i chain topology Flexible protocol Leverage existing standards or works

18 What is UFS? Universal Flash Storage Embedded & Removable devices 300MB/s with future scalability Employ a multi-device i chain topology Flexible protocol Leverage existing standards or works GOAL of UFS TG

19 Faster Interface Congested parallel interface Simple faster Serial Interface

20 Multi commands queuing One command at a time Multiple commands queuing

21 Multi commands queuing If NOT

22 How is it going to be? UFS is formed with simple 4 blocks Device Manager Application Layer UFS Command Layer Task manager UFS Transport Protocol Layer (UTP) UFS Interconnect Layer (UIL) UniPro M-PHY

23 How is it going to be? Easy for hardware development Device Manager More than just for UFS Application Layer UFS Command Layer Task manager UFS Transport Protocol Layer (UTP) UFS Interconnect Layer (UIL) UniPro M-PHY Adoption of MIPI specification - M-PHY version 1.0 for PHY Up to ~3Gbps for UFS 1.0 Over 5.8Gbs for UFS Unipro1.4/1.5 for link Simple bur flexible link layers MIPI specifications are on the final stage of release

24 How is it going to be? Easy to adopt in Software Device Manager Utilize exiting solutions; SCSI Application Layer UFS Command Layer Task manager UFS Transport Protocol Layer UFS Command (UTP) Layer UFS UFS Interconnect UFS Future Layer (UIL) SCSI Native extension UniPro M-PHY Work with SCSI commands & Architecture - SPC, SBC and SAM Min. options & features - Select & define for UFS specific usages cases - 10 ~ 15 commands No overhead for OS

25 How is it going to be? Simple but effect driver stack for UFS Device Manager Flexible device management Application Layer UFS Command Layer Task manager UFS Transport Protocol Layer (UTP) UFS Interconnect Layer (UIL) UniPro M-PHY Mobile usages centric device management -While work with SCSI & MIPI, UFS still fully mobile & Flash oriented devices Work with SAM4 Few extra efforts are needed

26 How is it going to be? Support major e-mmc features and more Boot Enhance Partitions Write Protect Multiple l Partitions Sleep & Reset RPMB (Security) and more.. Dynamic Capacity

27 What are these means..? 150MB/s UFS MB/s 40MB/s e MMC e MMC 4.4 ~ Single Task Multi-Task Asyn. & queuing

28 Coming soon
