4DS Memory logoAustralia-based RRAM developer 4DS Memory announced that it has signed an agreement with Belgium-based imec to develop a transferable manufacturing process for its technology. As part of the agreement the two parties will demonstrate the process with a 1Mbit test chip.

In October 2016 4DS raised $3 million USD to fund its ongoing ReRAM development activities. In October 2016 4DS also announced the fabrication of a working 40nm RRAM memory cell in collaboration with HGST, a subsidiary of Western Digital.

The 4DS memory cell is constructed using an advanced perovskite material, which has the same crystal structure as the inorganic compound calcium titanium oxide. The cells have no filaments and are so claim to be easier to scale compared to filamentary RRAM.
