Can i upgrade my mid 2012 macbook pro to use DDR4 ram ? Checking Apple > About this Mac > Memory i got the following

Your Mac contains 2 memory slots, each of which accepts
a 1600 MHz DDR3 memory module.

Which seems to suggest not, but i wondered if DDR4 was even around at the time my mac was made, is Ram a backwards compatible upgrade like placing a Sata SSD in a 10 year old device ?

No, the Mid-2012 MacBook Pro is in no way upgradable to DDR4 RAM.

To use DDR4 RAM a lot of things must be compatible with DDR4 - one of those is the CPU itself. The Intel CPU in the mid-2012 MacBook Pro does not support DDR4 RAM.

And no, DDR4 was not around in mid-2012. It was released to the market in 2014.
