Is it possible to access memory as a block?

I have a situation to load large amount of data multi-million of data to
memory for processing.
It’s memory intensive application. Analysis.

I have found that Hash is too slow, then I try Array but it’s overhead
of 20 or 40 byte make me run out of memory.

I try to find how to define a pointer to block of memory or create array
which less overhead.

Is that possible in ruby ?

Also the narray gem and A. Howard’s combination of the two:
