FLATE by default uses a 32K sliding window for best compression. The compressor can choose to use a smaller window and then the decompressor will require less RAM. If you want to be able to decode any ZIP file, then you need to allocate sufficient memory. I could allocate the memory dynamically, but the reason I did it this way is for very simple embedded targets with no malloc/free functionality. You're free to change it as you wish for your needs.
