memory_get_usage is the amount of memory being used at that time.

memory_get_peak_usage is the maximum amount of memory achieved during the entire execution of the script.

memory_get_usage: Returns the amount of memory allocated to PHP.

memory_get_peak_usage: Returns the memory peak allocated by PHP.

And the directive :

memory_limit: Directive of php.ini that sets the maximum amount of memory in bytes that a script is allowed to allocate.
