[ポスター講演]3x Write and 5x Read Speed Increase for RRAM with Disturb Free Bipolar Operation ○Sheyang Ning(Chuo Univ./Univ. of Tokyo)・Tomoko Ogura Iwasaki・Ken Takeuchi(Chuo Univ.) ICD2012-99 |

The RRAM high speed operation is handicapped by the need to verify during set/reset, and the limited read voltage for read disturb prevention. In this presentation, two circuit level optimizations, Bipolar verification and Reverse Read with Dynamic Write-Back are proposed to provide speed and reliability improvement. Bipolar verification reduces the Source Line (SL) charge/discharge time between program and verify modes. And Dynamic Write-Back allows higher read current, thereby reducing the read time with no read disturb degradation. Measurement of 50 nm $\mathrm{{HfO}_2}$ RRAM read disturb in forward and reverse directions supports the potential for 3${\times}$ write speed, 5${\times}$ read speed increase as well as read disturb immunity with the occasional write back operation. |
