while designing a SRAM i want to do scaling of transistors,L(length) is fixed by the technology node (90nm) but how do i decide the minimum width for the transistors?
 

The minimum width of the transistor is also fixed by the technology - it is minimum width of diffusion (or active or OD or - the name is different for different techologies). Check the Design Rule Manual. Note, that for SRAM bit cell usually exist different rules than for ordinary transistors (which is used in std cell as example).

I think you must do monte carlo simulations and choose the size that can pass these exam. I mean you must choose w and do monte and see if your system works well, if not you must for example increase w, and also you must plot BF and see that SNM is good or not!
