ExtremeTech takes a look at the current state of resistive RAM (ReRAM) technology, which is coming to the market in the near future. Full details over here.
There are several intrinsic advantages to ReRAM as compared to NAND flash. NAND has limited endurance, its lifespan degrades as process nodes shrink and cells become smaller, and the amount of error-correction required at each new node is steadily increasing. Performance gains have slowed since clocking NAND faster also tends to cause it to degrade, and the bulk of improvements are now delivered by improving either the NAND controller or the system interface — not the underlying performance of the NAND itself.
