Another First for 4DS - Significant Endurance Data

• Endurance was tested over a range of cell geometries from 50nm to 140 nm on two different wafers

• More than 1,000 cells tested

• In total nearly 1,000,000 cell states were changed

• The analysis of data indicates 4DS has functioning cells with correct memory operation, an essential feature for all memory manufacturers

• This significant milestone was achieved in collaboration with HGST, a subsidiary of Western Digital, the global leader in digital storage

• It is a first for the company and represents a significant and important step forward

• Additional individual cells were also tested and show endurance levels of well in excess of 10,000 cycles

4

Why is 97% significant?

To be relevant for Storage Class Memory endurance must have above 90% yield

• Memory manufacturers require yields in excess of 90%

• Above 90% is essential for mass market adoption of storage class memory

• Demonstrating the potential for ongoing and increasing levels of endurance is critical for a memory technology to be viable

• The current endurance results demonstrate that 4DS has consistently produced and tested working memory cells across a number of geometries from 50 nm to 140nm cells (and across separate wafers)

• The Company will continue to seek to replicate this endurance on smaller geometries and increase performance over all geometries to show statistically significant data trending

5

In October 4DS achieved a breakthrough 40nm milestone

• 4DS achieved working 40nm Interface Switching ReRAM cells for the first time in October 2016

• In the last 2 years, 4DS has consistently improved the scalability of cells from 800nm to 40nm

• 40nm represents a digital memory cell size which is smaller than existing non-volatile memory (NVM) technology, 3D Flash memory

• 40nm is vital for storage class memory – as the cells have no filaments, they are inherently scalable and do not have the same physical limitations as Flash or Filamentary ReRAM

• Patented technology demonstrates potential for 4DS to deliver memory cells which are significantly faster, cheaper and more energy efficient than existing Flash memory

6

Why is 40nm significant?

The biggest technical barrier for manufacturers of storage class memory is size

• Memory technology developers are in a race to achieve a resolution of 40nm

• Ability to scale down to 40nm is essential for mass market adoption of storage class memory

• Demonstrating the potential for ongoing scalability is critical for a memory technology to be viable

• 40nm is below the current size of conventional 3D Flash memory of between 45nm to 50nm

• The Flash market is estimated to be around US$40 billion

• 40nm represents the target cell size needed to prove the value of 4DS’ technology to memory makers

• Penetration of mobile devices, generation of digital content, proliferation of cloud storage, the emergence of the Internet of Things and the growth of connected devices drive the need for memory storage solutions

• NAND Flash (Flash) is a 30 year old non volatile memory (NVM) technology with diminishing ability to reliably scale to meet the exponential growth of data demands

• Industry experts cite resistive random access memory (ReRAM) as the leading emerging memory candidate to overcome the limitations of Flash, creating a multi-billiondollar emerging NVM market

• 4DS is developing breakthrough ReRAM technology for storage class memory– it enables higher density memory to run cooler, faster and longer than traditional technologies

• With a scalable 40nm cell, 4DS is demonstrating the potential for ongoing scalability, critical for a memory technology to be viable

• Unique, patented IP, wholly owned and developed in-house over the last 10 years

• A strategic partnership with HGST a subsidiary of Western Digital, a world leader in digital storage, is now into its 3rd year

Silicon storage facts

Apple is the biggest biggest Microsoft trialled an buyer of Flash in the in the underwater data world centre for 90 days to test its cooling benefits Amazon Web Services Consumers spend over adds more server US$2 trillion on capacity in a day than content, devices and Amazon.com had a services every year decade ago

Apple is the biggest biggest buyer of Flash in the in the world

Data centre space will grow to almost 200 million square metres in 2018

Household digital content is forecast to grow by 150% in the next 5 years

In 2020, demand for silicon storage capacity will outstrip production by 6 zettabytes (or nearly double the demand of 2013 alone)

The world is home to 7.2 billion mobile devices which are multiplying five times faster than we are

19

The Looming Storage Crisis

The world is facing an impending crisis in memory storage as technology struggles to keep up with demand

By 2020 demand for storage capacity will reach breaking point as the level of data created, replicated and consumed reaches 50 zettabytes – which is the equivalent of 12,500 billion DVD’s[1]

Flash memory, the incumbent technology, used in billions of mobile devices, tablets, laptops and data centres cannot scale smaller and cannot forever keep up with these levels of data generation

Innovation is needed to meet the future demands for higher density storage that is faster, has greater endurance and is smaller than current technology

2D Flash versus 3D Flash

Flash currently dominates the silicon storage market

2D Flash

• 16nm to 20nm cell size

• Limits are # of electrons

==> picture [163 x 44] intentionally omitted <==

3D Flash

• 45nm to 50nm cell size

• Limits are structural

Flash cannot scale forever

• It’s time for a memory innovation for GB silicon storage

• What is ReRAM?

• resistive random access memory

• non volatile: retains data when power is switched off

• changes in material resistance works as the storage mechanism

• Scalability and low currents are essential for GB silicon storage

Two approaches to ReRAM

The 4DS memory cell uses no filament to switch therefore no scaling issues

	Filamentary ReRAM	4DSInterface Switching (Non-Filamentary) ReRAM
Switching currents	High and don’t scale with cell size	Low andscale with cell size
On-off current ratios	Must be high due to widely fluctuating currents	Can be low due to muchmore stable currents
Scalability	Limited by wire current densities due to constant	Lower current allowssmaller cellsnot limited by wire
	switching currents	current densities
Cycling endurance	Constant filament formation and destruction	Does not rely on a destruction mechanism thereby
	results in eventual cell breakdown	increasing reliability
Data retention	High switching currents needed for long data retention	Low switching currentshelp data retention
Market sweet spot	Low density:	High density:
	IoT devices, small embedded memories	GB silicon storage for mobile and cloud

Why is 4DS ReRAM better placed?

4DS ReRAM technology is non-filamentary therefore has no filamentary scaling issues

4DS MOHJO™

• Oxygen exchange across hetero-junction

• A voltage pulse reversibly changes resistance

• Reversing voltage polarity switches resistance

• Non-filamentary switching mechanism
