How to Increase RAM On My Phone Without Root?

I'm Too Rid Of My Phone's RAM So I Want To Increase My Mobile's RAM Without Root.
Can Anyone Help?
Reason I'm Not Rooting My Phone Is I'm Having Fear Of Bricking My Phone And I Can't Afford A New One . :crying:
Is There Any Way To Swap My SD Card Memory To Ram ? I Will Be Thankful To You If You Reply.
