    fun fact: RAS# and CAS# seen on memory specs are the Row Access Strobe and Column Access Strobe timings in terms of clock cycles

    Wouldn't DRAM also be inherently slower because of the charge and discharge times of the capacitors (+ the transistor switching time) compared to the transistors simply switching in SRAM?

      Yes, I mentioned that reading from DRAM involves discharging and charging back the capacitor, which takes time.

    All I got from this is that memory performance has a lot of room for improvement even with existing technologies, and since it turns out that memory performance seems to be a major bottleneck, computers are posed to become a lot more powerful even without gigantic investments or a magic bullet

      Memory was always the most perfect part of a computer because everyone (server, client , mobile, graphics) needs it. Maybe this introduction is not to be taken as state of the art?

      @ well, clearly 3d cache chips have demonstrated that merely increasing l3 cache size leads to substantial performance improvements. It couldn’t have been so perfect before

      @ so 3d was existing technology?
