2. 3 rd Wave of Personal Computing Ethernet LAN Broadband Mobile Client- Server Cloud-Based Services Greater than 100 watts 10’s of watts Less than 10 watts WiFi Web Servers

3. 3 rd Wave Computing Infrastructure Processor And Modem eMMC V UFS LPDDR/2 V LPDDR3 FlashRAM Desktop class performance powered by a battery! Multiple cores and faster clock rate More channels, wider busses Increased capacity and transfer rate, Server class protocol Continuous Internet Landline speed Double (and then redouble) clock rate

4. Universal Flash Storage (UFS) The Next Generation Mobile Storage Built on e.MMC heritage Incorporate e.MMC features adopted by mobile systems for a smooth transition in mobile applications e.MMC SSD Technology

5. UFS Ecosystem The UFS Standard is developed in JEDEC JC64 committee Physical and link layer standards developed by MIPI The Universal Flash Storage Association (UFSA) focuses on ecosystem enablement and compliance certification Standards & Trade Associations UFSDevice UFS Enabled Chipset OS and Driver Host System Developer UFS is a pioneer in cross-standard integration MIPI Alliance

6. What is the UFSA? 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 certification management  Technical input into JEDEC / MIPI for future specifications Primary missions:  UFS technology promotion  UFS infrastructure enablement  Product compliance and certification management  Technical input into JEDEC / MIPI for future specifications

7. Principles of Certification Assure Devices and Hosts interoperate reliably –Uniform positive customer experience –Maximum breadth of compatible products –Allows products to differentiate on basis of core competencies –All parts of the specification are covered –Embedded and removable devices supported Maximize benefits to developers at minimum cost –Mix of interface and interop tests provides maximum coverage with least effort –Test matrix focuses on key predictors of conformance and interoperability –Technical test procedures developed by the experts in MIPI, Jedec, etc. who wrote the spec itself –“Class” certification supports product enhancement without recertification –IP protection integral part of the process Promote completeness and advancement of UFS/MIPI specifications –“Real life” input to specification developers Assure ultimate integrity of UFS brand –Vendor independent (3 rd party) testing, certified by UFSA –Integrated with UFSA logo program

9. Compliance Test Elements Test platforms –Provided by T&M vendors and IP developers –Instrumentation –Test fixtures –“Golden” references M-Phy, Unipro, UFS Test procedures –Developed by the specification experts in Jedec and MIPI –Rigorous, repeatable, technically clear –Maximum coverage of entire specification –Useful for development, debug, characterization and compliance UFS Test Specification –Developed by UFSA contributor members –Provided to UFSA adopter members –Defines certification test matrix –Clear description of test configurations –Simplifies development team scheduling and budgeting

12. Physical Layer Testing Typical platform components: –Metrology grade test fixtures –Oscilloscopes –Bit Error Rate Testers –Waveform generators –Network Analyzers –Time Domain Reflectometers Scope of testing –M-Phy Tx –M-Phy Rx –UFS channel (Tx ball to Rx ball) –Power integrity (future)

13. Protocol Testing Typical platform components: –Host, Device, snoop test fixtures –Oscilloscope protocol decoder –Protocol analyzer –Protocol generator/exerciser –Instrumented “golden” hosts and devices Scope of testing –Unipro –UFS Transport Layer (UTP)

14. Interoperability Testing Typical platform components: –Host, Device, snoop test fixtures –Set of “Golden” hosts (for device test) –Set of “Golden” devices (for host test) –Host test application or procedures –Phy/Protocol test equipment (for debugging) Scope of testing –Complete UFS HW/SW stack –Interoperation with defined set of “Golden” hosts/devices UFS Golden DeviceHost DUTGolden Host Device DUTs

15. Workshops, Plugfests And Certification UFS Workshop –Trial execution of UFS Compliance Test Specification –By Invitation only –Test and debug of the UFS CTS itself, test platforms and individual test procedures –Test results are anonymized before Compliance Committee review UFS Plugfest –Open to all UFSA adopter and above members under NDA –Standard CTS executed in private –Test results returned only to UFSA member undergoing test –Learnings used by CTC to improve CTS and generate feedback to partner organizations (individual test results are anonymized before committee review Certification Test –Provided as service by certified test houses (generally for-fee, no UFSA fee) –Results returned to company requesting test –Certificate of Compliance issued by test house to UFSA Adopters if all tests pass

16. Key Take-Aways 3 rd wave of personal computing requires complete infrastructure update UFS is the next generation of mobile mass storage engineered by the industry to enable 3 rd wave UFS is the first memory technology to be backed by formal certification program The UFSA is an industry driven organization supporting UFS ecosystem and assuring end-user confidence in UFS For more information: –www.universalflash.orgwww.universalflash.org –www.jedec.orgwww.jedec.org –www.mipi.org
