- High Density: By stacking memory cells in three dimensions, 3D PCM can achieve significantly higher storage capacities compared to traditional 2D memory architectures. - Non-volatility: PCM retains data even when the power is turned off, making it ideal for long-term data storage. - Fast Speed: PCM offers faster read and write speeds compared to NAND flash memory, which is commonly used in SSDs. - Durability: PCM cells can endure a higher number of write cycles before degradation compared to other forms of non-volatile memory.
