The second memory area is called **memory**, of which a contract obtains a freshly cleared instance for each message call. Memory is linear and can be addressed at byte level, but reads are limited to a width of 256 bits, while writes -can be either 8 bits or 256 bits wide. Memory is expanded by accessing (either -reading or writing) a previously untouched memory offset. At the time of expansion, -the cost in gas must be paid.

The EVM is not a register machine but a stack machine, so all computations are performed on an area called the **stack**. It has a maximum size of |
