PCM offers several advantages over traditional memory technologies: - High Speed: PCM can switch states in nanoseconds, providing faster read/write speeds compared to Flash memory. - Endurance: PCM can withstand a higher number of write cycles, making it more durable for applications requiring frequent data updates. - Scalability: Utilizing nanotechnology, PCM can be scaled down to very small sizes, allowing for higher storage density. - Non-volatility: Data stored in PCM remains intact even when the power is turned off, similar to Flash memory.
