  1. Adesto Technologies Corporation 2010 2010 2012 Adesto® named a finalist for Startup of the Year Adestoselected as one ofthe ‘Silicon 60’ emerging startups Adesto again selectedto the Silicon 60 - 2012

  2. What is CBRAM®? Less than 1mA Write Capable Less than 0.6V Write Capable Scalable to 1Xnm and Lower Multi Level Cell Capable Conductive Bridging RAM (CBRAM) is adisruptive memory technology platform that is highly scalable low power high performance which can be integrated at Back-End-of-Line in a standard CMOS processes. Sub 50ns Write Capable Large Dynamic Range Allowing Fast Access Bit Accessible for Read and Write 1 Transistor – 1 Resistor Cell (1T1R) DRAM Cost Structure Fully Compatibility with BEOL Processing

  3. CBRAM®– The Faster, Low Cost, Low Power Solution Non Volatile Implementation of CBRAM Technology DRAM Implementation of CBRAM Technology
