 ## Memory
 
-EVM memory is designed as a **word-addressed byte array**. In computer architecture, a word refers to a fixed-size unit of data that the CPU can process at once. EVM has a word size of **32 bytes**.
+EVM memory is a byte array of $2^{256}$ (or [practically infinite](https://www.talkcrypto.org/blog/2019/04/08/all-you-need-to-know-about-2256/)) bytes . All locations in memory are well-defined initially as zero.

 ## EVM upgrades
 
-While Ethereum protocol undergoes many changes in each upgrade, changes in EVM are rather subtle. Major change in EVM might break contracts and languages, requiring keeping multiple versions of EVM which introduces a lot of complexity overhead. There are still certain upgrades done on EVM itself like new opcodes or changes to existing ones which don't break their logic. Some examples are EIPs like [1153](https://eips.ethereum.org/EIPS/eip-1153), [4788](https://eips.ethereum.org/EIPS/eip-4788), [5000](https://eips.ethereum.org/EIPS/eip-5000), [5656](https://eips.ethereum.org/EIPS/eip-5656) and [6780](https://eips.ethereum.org/EIPS/eip-6780). These are proposing to add new opcodes except the last one which is especially interesting because it's neutralizing `SELFDESTRUCT` opcode without breaking compatibility. Another important upgrade to EVM which would mark rather a major change is [EOF](https://notes.ethereum.org/@ipsilon/mega-eof-specification). It creates a format to bytecode which EVM can understand and process more easily, it encompasses various EIPs and has been discussed and polished for quite some time.
