 ## VM Initialization
 
-Every time the VM runs, a single monolithic memory of size `VM_MAX_RAM` bytes is allocated, indexed by individual byte. A stack and heap memory model is used, allowing for dynamic memory allocation in higher-level languages. The stack begins at `0` and grows upward. The heap begins at `VM_MAX_RAM - 1` and grows downward.
