Artificial Intelligence
Nvidia Co-founder and CEO Jensen Huang described the emergence of artificial intelligence
(AI) as the beginning of a new industrial revolution, emphasising that there’s an ongoing global
‘awakening’ concerning AI technology.1
He also believes that, over the next four to five years, a trillion dollars’ worth of data center
infrastructure and hardware will be built across the world.2
TSMC founder Morris Chang recently revealed that customers have approached the company
to build up to ten new fabs for AI processors, indicating a significant increase in demand for
processors used in AI applications.3
Apple CEO Tim Cook, at the 2024 annual shareholder meeting, said his company is “investing
significantly” in artificial intelligence.4

4DS: The Right Memory for the Right Market at the Right Time
The New Age of AI Processing is built on decades of research into
neuromorphic processing and Neural Net modeling
These models require huge amounts of data and are the result of
billions of weighted matrix calculations
There is an explosion of new processor architectures in development
to overcome the speed, energy and memory bottleneck challenges
The introduction of a new non-volatile memory with high speed and

What is PCMO and why is it unique? continued
_
High O affinity by top electrode creates an oxygen depletion layer at the
surface junction (oxygen vacancies in the PCMO lattice)
Pulse of electric field pushes oxygen back into PCMO, filling vacancies
(very fast response: EPIR)
When the oxygen is present the cell conducts and is said to be SET
This is a reversible process, creating the on/off resistance states of the
memory cell
Total current is a function of this oxygen distribution across the oxygen
vacancies as determined by the one-shot programming

same chip

A need for a New Memory Solution Exists
“Difficult challenges gating development of beyond-CMOS devices include those related to memory
technologies, information processing or logic devices, and heterogeneous integration of multi-functional
components, a.k.a. More-than-Moore (MtM) or functional diversification.
One challenge is the need of a new memory technology that combines the best features of current memories
in a fabrication technology compatible with CMOS process flow and that can be scaled beyond the present
limits of SRAM and FLASH. This would provide a memory device fabrication technology required for both
stand-alone and embedded memory applications. The ability of a chip to execute programs is limited by
interaction between the processor and the memory, and scaling does not automatically solve this problem.
The current evolutionary solution is to increase cache memory, thereby increasing the floor space that SRAM
occupies on a chip. However, this trend eventually leads to a decrease of the net information throughput.
Volatility of semiconductor memory requires external long-term storage media that tend to be slow to
access (e.g., magnetic hard drives, optical CD, etc.). Therefore, development of electrically accessible
non-volatile memory with high speed and high density would initiate a revolution in computer
architecture. This development would provide a significant increase in information throughput
beyond the traditional benefits of scaling.”

The Speed Advantages of 4DS Memory
4DS has demonstrated reliable,
robust ReRAM programming with
a single 4.7ns write pulse
This improves on our previously
reported 9.5ns
The sub 5 nanosecond speeds are due
to Electric Pulse Induced Resistance
switching, which enables single shot
programming in the 4DS cell
This switching is faster than the DRAM
write window of 30ns and directly
translates to lower energy per bit
writing for the 4DS cell
Disclaimer: these graphs are based on best publicly available data and may not reflect actual state of the art for each technology.
The graph for the 4DS cell is estimated for the 20nm cell, based on scaling from 60nm actuals.
Persistence + Speed = Energy Savings
For permanent offline storage,
traditional NVM offers the best solution
For long persistence data 4DS offers
a low energy alternative
DRAM needs constant refresh
4DS needs no refresh within its
persistence window, and then can be
‘refreshed’ within the DRAM window
(‘hidden refresh’)
Disclaimer: these graphs are based on best publicly available data and may not reflect actual state of the art for each technology.
The graph for the 4DS cell is estimated for the 20nm cell, based on scaling from 60nm actuals.

Why Important? Warm Data Applications
Advanced computing always needs DRAM
for constant read and write (Hot Data), but
emerging Inference Engines for AI need data
at DRAM speeds that doesn’t change over time
(Warm Data)
Storage Class Memory – data storage that is
peripheral to the main processing data but not in
bulk storage – has consolidated behind CXL or
Compute Express Link
This supports many classes of memory behind
a standardized communications protocol
CXL is considered ‘Slow’ data when compared
to DRAM
Why Important? Analog Compute in Memory
Using SRAM is the common way of tackling the
bandwidth problem in AI processing
SRAM is the fastest memory for such uses
However the number of weights is limited by
SRAM cell size (6T) and # bits per weight needed
A scalable analog alternative could increase
total number of weights and simplify the vector
operations
Conversion back to the digital domain will still
be needed
