[R] memory limit

when I try to import a microarray CEL batch, I get this error message:

> myAB <- ReadAffy ()
Error in .Call("read_abatch", filenames, rm.mask, rm.outliers, rm.extra,  : 
  cannot allocate vector of length 1287151200

which, assuming the value is in bites, is below my RAM values (3 Gb recognized by Windows).

The isse is, when I try to do

 memory.limit (size =   3000 )

the error doesn't resolve, and when I type

> memory.size ()

I always get 
[1] 26.85

I'm confused here. Can anybody help me?
