Remembering function values AND compile

Dear MathGroupers,

To speed things up I could use a Compiled function in my program.
The program is also likely to calculating the same function value
several times so I could use the "remembering" facility

f[x_,y_,z_]:= f[x,y,z] = blah blah

to prevent re-evaluation of f for a particular set of x,y,z.

My questions are:

Can I combine Compile with the "remembering" of function values ?
Would this be faster than just using Compile ?

Thanks in advance,
