Question [Q] How to increase RAM by swapping internal phone storage


I have Micromax canvas music A88. Storage detail of my phone is:
RAM : 512 MB
ROM : 4GB NAND Flash Memory
Internal Memory : 503MB ( For apps installation), 1.93 GB (For user data)

I just want to transfer memory from 1.93 GB (For user data) to RAM and I think it will not affect to ROM as seperate memory is allocated for ROM.

So how to transfer memory from internal storage to RAM...??
