Reconstruct determinant of the Hessian

Hi all,
in quasi Newton methods in optimization the Hessian of the target function is reconstructed. This means that one needs to store a matrix in each step. If one needs only the *determinant* of the Hessian, is there a trick to get it without storing the whole matrix?
Thanks
Karl
