The Kernel's Write: Application Read-Only Memory (opens in new tab)

Alongside power, DRAM has become a major limiting factor in datacenter growth. As DRAM's cost-per-bit has plateaued over the past decade, a class of emerging memory technologies, called Long-term RAM (LtRAM), offers a path to denser and cheaper main memory. However, LtRAM has three main drawbacks: asymmetric read/write latencies, limited endurance, and coarse write granularity. In an attempt to isolate software from these drawbacks, LtRAM techno...
