Basic differences between old and new MRAMs

basic commercial advantages ... materials dependent

• pros

faster switching than SRAM, but slower than charge-based DRAM?

more energy-efficient than DRAM?

"collective switch" of stt-mram has very different behaviour than a single-electron-based physics of non-magnetic Tunneling Junctions of DRAM/SRAM - what is better and what is worse?

Write power is low according to what work/references (according to Table on page 7 here)?.... errors on writing are widely discussed, pls find a reference too (MT)

• cons

still more expensive than DRAM... so far?

• trade- offs
