When running, SRAM consumes a lot more power and space than almost any kind of DRAM. 2-4 transistors per cell vs 1, if nothing else. A big problem is that the CMOS process for dense, low power, fast RAM is different than what you want to use for a CPU. And even between DRAM and SRAM there's a pretty big difference.
