With endurance of 100x to 1000x that of flash, this seem like it would be a poor replacement for DRAM (but definitely a good replacement for flash and spinning disks, depending on the cost/GB). I searched, but could not find any obvious/easily accessible endurance summaries for DRAM (which I realized I had never given much thought). Does anyone know of any good sources for this?
- jeffbee 5y agoDRAM doesn't have program/erase wear-out. The device is essentially a capacitor. There is no endurance limit for tiny capacitors. DRAM does have a retention limit, only a few milliseconds. That's a drawback.
- pitaj 5y agoThere is an endurance limit for any sufficiently small electronic device. Electromigration. With capacitors specifically, dielectric will eventually fail.

- jeffbee 5y agoOK, but they don't wear out from that based on write cycles, they would wear out from that based on power-on hours.
