=Static Storage=
The static memory storage is 322 entries big and located at 0x142A760C0 (v1.07).<br>
The entries have a max content size of 32 bytes.<br>
Due to this restriction the memory de/allocation in this storage is way faster than in the dynamic storage.<br>

=Dynamic Storage=
The dynamic storage is allocated with the function at 0x140361A40 (v1.07).<br>
Two HLib entries will be added, one at the start and one at the end of the allocated memory.<br>
After the first HLib entry a new fREe entry will be added and looks like this.<br>
This entry has the previous entry pointer set to the first HLib entry and the next entry pointer set to the HLib entry at the end.<br>

=Free Storage=
To free storage the function 0x14049CDD0 (v1.07) is used.<br>

=Allocate Storage=
To allocate storage the function 0x14049CB40 (v1.07) is used.<br>
