It's very difficult for a non-volatile memory to attempt the speed typical of SRAM or DRAM. Basically some barrier is needed to preserve a state and this barrier would naturally limit switching speed unless using higher voltages. Furthermore, being a series resistance, the MRAM should dominate the resistance yet not load the circuit so much. On the other hand, keeping this resistance load low would prevent scaling.
