4DS Memory

4DS Memory logo4DS Memory, based in Australia, develops non-filamentary RRAM based memory for next generation storage devices. The company owns an IP portfolio developed in house to create high density gigabyte storage.

In 2014, 4DS signed a joint-development agreement with HGST, a Western Digital subsidiary, to optimize 4DS's technology for the gigabyte storage market. The agreement was renewed in July 2016 for a further 12-month commitment. In October 2016 4DS announced it developed a 40nm working RRAM cell, and in November 2017 4DS announced a collaboration with imec to develop a manufacturing process for its technology.

Sandisk

Sandisk logoSanDisk, owned by Western Digital is a leading Multinational flash memory developer that provides flash memory storage solutions for data centers and mobile devices. The company also develops RRAM memory technologies.

In 2015 SanDisk signed a long-term partnership with HP to co-develop RRAM technologies and expects RRAM products to enter the enterprise storage market by 2018.

Adesto Technologies

Adesto logoAdesto was established in 2007 to develop a low-power RRAM-memory type called Conductive Bridging RAM (CBRAM). Adesto's is already shipping CBRAM chips, targeting the EEPROM and NOR flash markets.
