MemoryBlocks can be compared with each other using the "=" operator.
MemoryBlocks are considered equal for these conditions:
- The MemoryBlocks are the same object
- Both MemoryBlocks' data point to the same location
- Both MemoryBlocks' size and content are the same
There is no concept of one MemoryBlock being greater than or less than another MemoryBlock.
