With Resistive Memory adoption to replace NAND, how will evolve IP forces involved in the next years ?
DESCRIBING THE IP SITUATION
The Resistive Memory technologies involve more than 100 different applicants. The main IP holders in the domain are Samsung, Toshiba and SK Hynix. With growing market, new players are emerging and reshaping the IP landscape, especially Hewlett Packard is coming into playground strongly with new resistive memory type (memristor), Crossbar that unveiled architecture breakthrough innovation or Adesto Technologies that acquired Qimonda CBRAM Memory IP.
In recent years, emerging non volatile memories have been enthusiastically studied in order to replace Flash Memory that faces among others, scalability challenges. Among these candidates, Resistive Memory has been extensively studied as one of the most promising candidates for the next generation of memory technology due to excellent memory performances. Indeed, Resistive Memory, that exhibits resistive switching between a high resistance state and a low resistance state, has overwhelming advantages in easy fabrication, simple structure, excellent scalability, fast switching, high integration density, and good compatibility with the current complementary metal oxide semiconductor (CMOS) technology.
The application potential of the new emerging resistive memories - as metal oxide resistive switching memory (OxRRAM), conductive-bridge memory (CBRAM) or conductive metal oxide memory (CMOx) - covers the standalone memory technologies (as NAND and DRAM), but offers also potential for exciting new applications and markets, as new functionality coupled with logic circuits to enable block power-down, or use as synapses in neuromorphic circuits. Some devices are already on the market: 1Mb 130 nm CBRAM device of Adesto Technologies since 2011 and ReRAM embedded MCU of Panasonic since 2013. Besides, the 16Gb CBRAM of Micron and Sony that will be commercially available this year will allow the development of a mainstream market.
