Abstract

In this letter, we propose an effective route to reduce the cell-to-cell variability in 1T-1R-based random access memories (RRAM) arrays by combining the excellent switching performance of Hf1-xAlxOywith an optimized incremental step pulse with verify algorithm for programming. The strongly reduced ...
