You don't. That is presently the limit in Photoshop.
(at at 250 Gig for a flag RGB 8 bit/channel image, it's also rather time consuming to read or write)

Are there any other software and file formats to allow me to go bigger than PSB?

Not much can work larger than Photoshop.
And a few layers in a 300k x 300k document would hit a TB.

But at that size, just opening and saving is going to take hours.

When I edit some files on Photoshop that are 10 gigs in size they create temp files as large as 60 gigs and eat up my hard drive space. Do you know a way I can stop photoshop from creating these files.

You can reduce the number of history states to reduce the size of the files. But that history takes space, and that disk space is necessary once you run out of RAM.

Even at 1.1 GB it takes a while to process anything, I often save as and then purge all (the save as is for insurance).  It helps.  I mostly run files of 100 - 300 MB at a time.
