04:49PM EDT - Here we go
04:49PM EDT - Derek Dicker, CVP of the Storage Business Unit
04:49PM EDT - Starting with the background of Micron
04:50PM EDT - Founded 1978
04:50PM EDT - Originally a design consultancy for semiconductor design
04:50PM EDT - Went from services to building DRAM
04:51PM EDT - Based in Boise, ID
04:51PM EDT - 1981, first 64kb DRAM
04:52PM EDT - 2007, SLC NAND
04:52PM EDT - 2011, MLC NAND
04:52PM EDT - 2016, TLC NAND
04:52PM EDT - 2018, QLC NAND
04:52PM EDT - About 35000 employees, revenue $30b/q
04:53PM EDT - In 2000-2007, 250 billion GB created annually
04:54PM EDT - In 2008-2016, 7000 billion GB created annually
04:54PM EDT - In 2017, 22000 billion GB created
04:55PM EDT - Revenue generated from memory, (NAND, DRAM, NOR) $130B+
04:55PM EDT - All driven by the next generation networks
04:55PM EDT - Forcast 62000 billion GB in 2021
04:56PM EDT - In Client PC, 80% PC SSD adoption anticipated by 2021, 2x expected average cap increase
04:58PM EDT - In Mobile, 100x network bandwidth increase with 5G by 2021, 1.7x increase in DRAM and 3x NAND per phone anticipated
04:59PM EDT - Some phones today have 1TB of NAND
04:59PM EDT - In Automotive, vehicle sensors projected to increase to 200 per core, 22 billion sensors a year generating data by 2020
05:00PM EDT - In IoT, sensor data growing at 50x business data, 3 image sensors for every human anticipated
05:01PM EDT - Big aspect is datacenter
05:02PM EDT - AI Workloads unleash the need for more memory and storage. Micron expects 6.8x DRAM per server in 20201
05:03PM EDT - Going from 366GB for a standard server to 2.5TB for an AI server
05:03PM EDT - Micron expects capacity will increase by 1.8x for AI
05:04PM EDT - Now discussing NVIDIA DGX-2
05:04PM EDT - 1.5TB DRAM, 30TB NAND in a single DGX-2
05:04PM EDT - AI and DL are changing the IO patterns of the datacenter
05:05PM EDT - IO Pattern for DL is 5000:1 read-to-write ratio
05:05PM EDT - traditional datacenter IO is 4:1 read-to-write
05:05PM EDT - Means a need for things that are read intensive
05:05PM EDT - The trends mean that there is a need to span the memory and storage continuum
05:06PM EDT - Micron sees a lot of reasons to see the demands of the future
05:06PM EDT - Need to deliver solutions through innovation
05:06PM EDT - Micron Innovation: CMOS under the array
05:07PM EDT - Taking the CMOS logic under the array, compressing the x and y dimensions
05:07PM EDT - get more space to add more memory
05:08PM EDT - Also innovation: Array Stacking
05:08PM EDT - rather than adding layers, just add stacks
05:09PM EDT - Russ Meyer to the stage, CVP of NVM Integration
05:10PM EDT - 4th Gen 3D NAND is coming
05:11PM EDT - Low resistance metallization to improve perf
05:11PM EDT - This technology is set to scale into 200 tiers
05:11PM EDT - switching from floating gate to charge trap cell
05:12PM EDT - Going after write bandwidths
05:12PM EDT - Lower energy per bit
05:14PM EDT - 5210 ION SSD is world's first QLC drive: read focused for enterprise
05:15PM EDT - What the ideal workload for QLC is
05:15PM EDT - 4.6x better perf with fewer drives
05:16PM EDT - replacing the HDDs in the datacetenter
05:16PM EDT - Replacing four 10K RPM HDDs with one QLC SSD for 4x higher perf
05:17PM EDT - QLC can't beat 10k RPM HDDs on $/GB, but has lower TCO thanks to lower power, higher density and performance
05:17PM EDT - 3 node Ceph cluster using 24x 8TB drives for 70 Gbps read
05:17PM EDT - for CDNs
05:17PM EDT - New storage stack software for 2x better throughput with 4.5x reduction in write amplification
05:20PM EDT - Micron vision: transforming how the world uses information to enrich life
05:20PM EDT - Micron has four breakout sessions at FMS
05:20PM EDT - That's a wrap. SK Hynix is next! Check the front page for our live blog
