Today Micron announced the production of 8GB DDR4 NVDIMM, the company’s first commercially available solution in the persistent memory category. Persistent memory delivers a unique balance of latency, bandwidth, capacity and cost, delivering ultra-fast DRAM-like access to critical data and allowing system designers to better manage overall costs. With persistent memory, system architects are no longer forced to sacrifice latency and bandwidth when accessing critical data that must be preserved.

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?

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
