Wired News reported today that both Moterola and IBM have been developing a single type of memory the will supposedly replace all other forms of ram/rom and what not.
How many fundamental changes to the personal computer have you noticed over the last three years? Besides ever increasing performance from the four major chip makers a lot has been developed and a lot of new technologies are finally being implemented. First the development of PCI- X began so much a new concept but an improvement of an extreme measure. PCI –X more/less doubles the speed of the current standard 66 MHz PCI bus and revs it up to 133 MHz notice twice the clock speed but nearly 6 times the bandwidth (see PCI-SIG).
Then came the development of Serial ATA (SATA ) a technology that promised to speed up the traditionally slowest part of the PC – the hard drive by instead of sharing the ATA bus with other devices, devoting a direct connection to each device increasing the theoretical speed and the reliability of hard drives and other devices that utilize the ATA architecture.
So what’s on the horizon? MRAM, short for magneto resistive random access memory looks like the future (see wired news ). What’s so different compared to normal ram and flash type ram? Well in a word, nothing. MRAM is just as fast as if not faster then DDR/RD/SD type rams but is also non-volatile (compact flash, smart media ect…) The development of MRAM is being development of MRAM is being funded primarily by the Defense Advanced Research Projects Agency (DARPA) so specification wars aren’t expected to arise. For further details on the MRAM spec see Tech Target.
