The Right Memory for the Right Market at the Right Time
4DS Memory Limited (ASX: 4DS), with facilities located in Silicon Valley, is a semiconductor technology company bringing high bandwidth, high endurance, persistent non-volatile memory to advanced CMOS process nodes. Its technology, known as Interface Switching ReRAM, features tunable persistence and low energy per bit for today’s most challenging compute intensive and AI processor applications.
Established in 2007, 4DS owns a patented IP portfolio, comprising 34 USA patents, and is the first company to develop PCMO ReRAM, on an advanced CMOS processing node.
4DS has three important industry relationships: a development agreement with Belgium based imec, a world leading research and innovation hub in nano electronics and digital technologies; a design agreement with Infineon Technologies AG, Germany’s largest semiconductor manufacturer and one of the ten largest semiconductor manufacturers worldwide; and a joint development agreement with Western Digital subsidiary HGST, a global leader in storage solutions.
Pioneering Technology
The Memory That Breathes©
4DS Memory’s technology is a type of Resistive Random Access Memory (ReRAM) where the 4DS cell is based on a different physical switching mechanism to other ReRAMs on the market, which gives us high speed, high endurance and tunable retention characteristics. (This is also called Area based Interface Switching.) These characteristics place 4DS in a unique application space, namely high bandwidth persistent memory for Big Data and Artificial Intelligence (AI) applications.
4DS: Enabling Future AI
The exponential advances in AI that we have seen are the result of 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. However, the semiconductor technologies needed to run these models have not been able to keep pace, and overcoming these barriers is critical for future AI systems development. While there has been an explosion of new processor architectures in this field, memory technology has not been able to keep pace. The introduction of a new non-volatile memory with high speed and high density ‘would initiate a revolution in computer architecture’*. 4DS is potentially that memory, at the right time, for the most important market in the world.
