What Are We Announcing?

On November 10, Micron is announcing

production of the company’s first commercially

available Persistent Memory solution, a DDR4

NVDIMM.

– Combines DRAM Performance with NAND Flash

– Accelerates Application Performance by Delivering

Faster Access to Large Data Sets While Removing

Bottlenecks

– Provides a new choice in architecture that allows

customers to store data close to the processor


Persistent System Memory

Persistent memory is a new addition

to the compute/storage hierarchy

that provides non-volatile, low-

latency memory close to the

processor.

Persistent memory accelerates

application performance

– Removes constricting I/O bottlenecks

– Greater flexibility in data management

Non-volatile memory on the DRAM

bus significantly optimizes data

movement, delivering faster access

Will provide a bridge to future storage

class memory solutions such as 3D

XPoint™ technology.

Understanding the Performance Gap: Latency

Translating latency into a real world example…

How long would it take to locate and retrieve a key ingredient – like a tomato - to

make a pizza using locations based on DRAM, PCIe SSD or 10K HDD?

DRAM…walking to

your fridge to get a tomato…

6 seconds

PCIe SSD…driving to a

country produce stand to get a fresh tomato…

2.2 hours

10K HDD…growing and

ripening a tomato in your

garden….

46 days


The Impact of Persistent Memory

• A growing number of applications— Require frequent access to large data sets

— Are sensitive to down time

— Have performance limitations due to I/O bottlenecks

• Extends life of SSD

and improves

performance for

write-intensive

apps

• >100x lower write

latency versus PCIe SSD

w/ unlimited endurance

• Scalable unified RAID

performance for SSDs

and HDDs

Case #1: Write Caching

For MLC SSDs

Case #2: Low Write Latency

Persistent Storage

Case #3: Unified Open Software-

Defined Server RAID


Persistent Memory & NVDIMM

• NVDIMM is the persistent memory solution

available today.

• Micron’s NVDIMM is capable of delivering

the performance levels of DRAM combined

with the persistent reliability of NAND:

— Combines NAND Flash, DRAM, and a

power source into a memory

subsystem

— Delivers DRAM read/write performance

and backs up its data if power is

interrupted

UltracapacitorModule

Self-contained energy source for backup operation during

power failure

Flash management, high-speed DMA, Status

Onboard DRAM & NANDDRAM performance and

Flash non-volatility

Why Micron

• Committed to the development of persistent memory

technology

• Delivering on the promise of persistent memory with a

DDR4 NVDIMM solution

• Leading the way on future persistent memory

development, spearheading R&D efforts on promising

new technologies such as 3D XPoint™ technology, which

will be available in 2016 and beyond.


NVDIMM – More DetailsMicron will be offering three DDR4 NVDIMM products:

1. 8GB DDR4 NVDIMM w/legacy firmware• RDIMM architecture• DDR4-2133 • Single rank x4 configuration• In production now• Backup power source: PowerGEM or persistent 12V routed to DRAM slot

2. 8GB DDR4 NVDIMM w/JEDEC firmware • RDIMM architecture• DDR4-2133 • Single rank x4 configuration• Engineering samples available now; Production in early 2016• Backup power source: PowerGEM or persistent 12V routed to DRAM slot

3. PowerGEM (ultracapacitor) for 8GB NVDIMM• Back-up time: ~40 seconds (the time required for the NVDIMM controller to copy the DRAM content to NAND when power is lost)• Back-up power source: tethered ultracapacitor• 2 ½” Drive bay form factor


Understanding the Performance Gap: Bandwidth

Translating bandwidth into a real world example…

How long would it take to commute to work if using different routes based on

DRAM, PCIe SSD and 10k HDD?

DRAM… speeding

on a 256 lane autobahn…

PCIe SSD…driving a

16 lane highway…

10K HDD…puttering

along a 2 lane alley….
