Challenges for high-density 16Gb ReRAM with 27nm technology

Abstract

Enabling a high-density ReRAM product requires: developing a cell that meets a stringent bit error rate, BER, at low program current, integrating the cell without material damage, and providing a high-drive selector at scaled nodes. We discuss ReRAM performance under these constraints and present a 16Gb, 27nm ReRAM capable of 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">5</sup> cycles with BER <; 7×10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-5</sup> .
