With the scaling of DRAM process technology, the reliability problem of modern DRAM is emerging. A representative problem is Row Hammering, a phenomenon in which values stored in cells of adjacent rows are unintentionally bit-flipped by intensively activating the same row in the bank. One of the representative methods for overcoming the row hammering problem is PARA (Probabilistic Adjacent Row Activation), which uses probability-based additional row refresh techniques. In this paper, we propose E-PARA, complementing the existing PARA by adding a memory address buffer. Our evaluation shows that the energy consumption in the E-PARA model to prevent row hammering decreased by 31.08% compared to the previous PARA model, and the additional cycle decreased by 85.60%.

Deposition of silicon nitride films on silicon wafer were produced by using the plasma enhanced chemical vapor deposition with SiH₄-N₂ gas mixture. In order to investigate their properties, the electrical properties such as I-V characteristics, breakdown strength and C-V characteristics were measured. As results of the present investigation, the silicon nitride films have good insulation properties and breakdown strength of 7 ㎝MV/㎝. Also, the electrical conduction mechanism of the films were proof the Poole-Frenkel emission.
