1 How Storage Solutions Are Accelerating the Mobile Revolution Stephen Lum, Mobile Memory Product Marketing Hank Lai, Mobile Memory Product Planning Samsung Electronics, AHQ JEDEC Mobile Forum 2014 Copyright 2014 Samsung

2 Mobile Trend & 2014 Outlook Mobile Gadget Evolution Faster Connectivity Everything Connected New Killer Apps

3 Future Mobile Era - Data Explosion High storage growth expected in the future mobile era Mobile Traffic [PB/Month] IT Storage [ZB/Year] 1ZB=1Trillion Gigabytes X Tablets Smart Phones 21X

4 Smartphone Adoption Continues to Grow Over 80% of world s population has a mobile phone But only ~1/4th of the world s population has a smartphone Smartphone adoption still has huge upside for global penetration

5 Tablet Growth Has Been Phenomenal Tablet shipments surpassed DT/NB PC s in Q4-12 < 3 Yrs from Intro! Large screen computing device demand is strong Mix favors Tablets, not PC s Sources: KPCB, Morgan Stanley Research, Gartner

6 Mobile Storage What s Needed? High Performance Efficiency/Responsiveness Instant Play Multi-tasking Multi-Processing Productivity Apps PC-like Gaming Fast App Loading/ App Swapping Low Power Longer Battery Life Quad/Octa-Core CPU Multi-tasking Larger screens AOAC Instant ON Security Reliability New Security Challenges Robust Memory Enterprise/BYOD Mobile Shopping High Capacity More Memory More Apps, Richer Apps HD Video, High Res Photos 3D Graphics/4K Content Small Package Thinner is Better High Capacity in Small Form Factor Small & Slim Pkg: Z-height is Key

7 UFS: Natural Migration for Mobile Evolution Higher Performance & Efficiency with lower total power Continued Scalability for future 1.2 GB/s Better, faster, scalable for future Higher efficiency UFS 2.x (tentative) 600 MB/s SCSI Based Async Protocol UFS 2.0 UFS 2.0 Good, sufficient performance, fuel-efficient 400 MB/s Memory Card Based Sync Protocol emmc5.0 emmc5.1 emmc4.5 emmc4.3 emmc4.4 emmc ~16

9 Command Queue Improves UX Better Movie Playback - Play UHD movie while copying files - CQ reduces frame drops and improves playing time Reduced Apps Execution Time - Scan operation of vaccine program (V3, Naver) - Apps switching time Improve play time (25%) 15sec 10sec (Reduce 33%) Booting Time - Booting time reduced from power-on to entering lock screen Benchmark - Improved Random Read performance Improved 2.5x

10 Read While Write Performance w/ CMD Q CQ device shows shorter latency for Read Request during low priority writes For 512KB Request, 5.0CQ device is ~50% shorter than 5.0 For 3MB Request, 5.0CQ is ~30% shorter than 5.0

11 emmc CQ for Multi-thread thread S/W Multiple cores enable multiple threads.. Improved Playback while doing File Copy 5.0CQ driver passes priority to the device Reduced buffering improves play time 25% Reduced Application Load Time CQ CQ maximizes multi-core capability 1 Thread 4 Threads Improved random reads for more than 4 threads Reduced application load time by 33% (15s 10s)
