Likely it will be a long time before MRAM can compete with DRAM and NAND flash for universal application. A cellphone spends most of its life sleeping so maybe theis MRAM stuff will be nice for extending battery life etc.

    SDRAM is power hungry during sleep mode ( a few mA) and has a slow sleep/wake-up sequence. This is not very nice for some devices like cellphones.

    I think the most likely use we'll see for MRAM in the short term is having, say, 256kB of MRAM in a cellphone for running the cellphone engine and using SDRAM etc for the extended features.

  31. Here is an analogy by fredistheking · · Score: 2, Informative

    When you burn a cd does ambient light destroy the medium? No. Just like a strong enough light source (for example, the burning laser in your xDRW drive) could destroy or alter the data on it. There is not going to be a strong enough field to do this accidentally, the fields put off by electronics are too small to be of much concern. If there even was a problem, parity algorythms could be used the same way they are in larger magnetic media (RAID). It is certain that a stong enough magnetic field could depolarize the data but I doubt the field is that "loose". Furthermore a magnetic field is inversly proportional to the square of the distance to the source ( E~1/[R^2] ) which decays rather rapidly as the distance increases. Electronic devices may operate at a high frequency but the power (amplitude)is too low to low to generate the field that would be required. Electic/Magnetic Field Equations

    I used to keep my computer on 24/7. Then I put it in my bedroom. Did I mention I have a big-ass server case with six fans? Nowadays, I'd rather wait the three minutes for boot-up and get a decent night's sleep; I'm funny like that.
