Memory error while saving dictionary using pickle

[Nagu]

I am trying to save a dictionary of size 65000X50 to a local file and
I get the memory error problem.

How do I go about resolving this? Is there way to partition the pickle
object and combine later if this is a problem due to limited resources
(memory) on the machine (it is 32 bit machine Win XP, with 4GB RAM).

Please advice.

Thank you,
Nagu
