Demonstrator application, page-104

The following snippet is the only reference I can find to these later patent applications, this is from 30/7/2020:

US Patent granted in January 2020 related to RRAM memory and methods of manufacture. Pending patent applications related to further aspects of this technology

The granted US patent only referenced strontium titanate as one example of metal oxides and perovskites that could be used as a material for their memory ink.

Then there is this very vague hint in the September 2020 quarterly report released 27/10/2020:

The Project will be led by UNSW Associate Professor Dewei Chu, co-inventor of the Nanocube Memory Ink and will produce metal oxide based nanomaterials for printable, flexible and cost-effective memory devices. The project aims to develop next generation printable memory devices with low cost and excellent stability.

And from 2/11/2020:

A recent patent filing3 also covered a Nanowire Ink and memory array design for potential use in other flexible electronic devices such as OLED devices, sensor devices and neuromorphic computing devices

Near Term Results
• The Nanocube Memory structure and operation allows it to combine computing and memory in one place in a way similar to how biological neurons operate. The Company will test the Nanocube Memory for its potential in flexible, transparent, brain-inspired (neuromorphic) computing. A series of significant synaptic functions will be emulated.
