The macro ``__NOINIT_ATTR`` can be used as attribute to place data into ``.noinit`` section. The values placed into this section will not be initialized at startup and should keep its value after software restart.

By applying the ``EXT_RAM_NOINIT_ATTR`` macro, non-initialized value could also be placed in external RAM. To do this, the :ref:`CONFIG_SPIRAM_ALLOW_NOINIT_SEG_EXTERNAL_MEMORY` needs to be enabled. See :ref:`external_ram_config_noinit`. If the :ref:`CONFIG_SPIRAM_ALLOW_NOINIT_SEG_EXTERNAL_MEMORY` is not enabled, ``EXT_RAM_NOINIT_ATTR`` will behave just as ``__NOINIT_ATTR``, it will make data to be placed into ``.noinit`` segment in internal RAM.

通过使用 ``EXT_RAM_NOINIT_ATTR`` 宏，noinit 数据也可以放入外部 RAM 中。为此，需要启用 :ref:`CONFIG_SPIRAM_ALLOW_NOINIT_SEG_EXTERNAL_MEMORY`，可参考 :ref:`external_ram_config_noinit`。如果没有启用 :ref:`CONFIG_SPIRAM_ALLOW_NOINIT_SEG_EXTERNAL_MEMORY`， ``EXT_RAM_NOINIT_ATTR`` 会和 ``__NOINIT_ATTR`` 一样，将数据放入内部 RAM 的 ``.noinit`` 部分。
