Module Details
---------------

mstore
~~~~~~


.. function:: mstore(evm: ethereum.spurious_dragon.vm.Evm) -> None
   :noindexentry:

   Stores a word to memory.
   This also expands the memory, if the memory is
   insufficient to store the word.

   :param evm: The current EVM frame.




.. undocinclude:: /../src/ethereum/spurious_dragon/vm/instructions/memory.py
   :language: python
   :pyobject: mstore

mstore8
~~~~~~~


.. function:: mstore8(evm: ethereum.spurious_dragon.vm.Evm) -> None
   :noindexentry:

   Stores a byte to memory.
   This also expands the memory, if the memory is
   insufficient to store the word.

   :param evm: The current EVM frame.




.. undocinclude:: /../src/ethereum/spurious_dragon/vm/instructions/memory.py
   :language: python
   :pyobject: mstore8

mload
~~~~~


.. function:: mload(evm: ethereum.spurious_dragon.vm.Evm) -> None
   :noindexentry:

   Load word from memory.

   :param evm: The current EVM frame.




.. undocinclude:: /../src/ethereum/spurious_dragon/vm/instructions/memory.py
   :language: python
   :pyobject: mload

msize
~~~~~


.. function:: msize(evm: ethereum.spurious_dragon.vm.Evm) -> None
   :noindexentry:

   Push the size of active memory in bytes onto the stack.

   :param evm: The current EVM frame.
