|Abstract:||Asymmetric PCRAM cells were investigated and when the upper contact opening just offset from the bottom contact opening, the reset current was reduced tremendously compared to that of a conventional symmetrical structure due to the improved heat confinement. When the phase change material, Ge 2Sb2Te5 was sputtered with a N2/Ar gas flow ratio of 0.2, the asymmetric PCRAM cells lasted 2.4 × 1010 cycles and it lasted 10 times longer than N-doped symmetrical PCRAM cells. © 2008 Materials Research Society.|
