- Data access speed
- Storage density
- Lower overall cost of ownership
Storage class memory (SCM) occupies a critical middle ground in the spectrum of memory storage, as it’s much more performant than non-volatile NAND flash memory, but not as costly or energy dependent as volatile memory like DRAM or SRAM.
Within this SCM category, PCRAM (phase change memory alloy) is in the sweet spot, capable of delivering <20-ns access times, faster than typical SCM and can be just a hair below DRAM in speed performance. PCRAM can enable:
- Increased data access performance - 1000x that of NAND
- Higher storage density - 4x higher than DRAM
- Extreme durability - 1000x or more cycle endurance than NAND
