Download the 2020 Memory


The Stanford Memory Trends is a compilation of tables and figures summarizing the various memory metrics reported for RRAM, PCM, CBRAM and STTMRAM. In the latest version, we also include standalone memory selector, IPCM, hybrid 1S1R cell and analog RRAM that shows gradual conductance modulation characteristics in separate sheets. The tables include commonly sought parameters (including write current, cell size, switching time, endurance, retention etc.) presented in conferences and journals including IEDM, VLSI and ISSCC from 2001 and onward. The figures capture the high level trends of how certain parameters correlate to each other (such as cell area vs write energy).
