 An additional configuration item, :ref:`CONFIG_SPIRAM_MALLOC_ALWAYSINTERNAL`, can be used to set the size threshold when a single allocation should prefer external memory:
 
-- When allocating a size less than the threshold, the allocator will try internal memory first.
-- When allocating a size equal to or larger than the threshold, the allocator will try external memory first.
+- When allocating a size less than or equal to the threshold, the allocator will try internal memory first.
+- When allocating a size larger than the threshold, the allocator will try external memory first.
 
 If a suitable block of preferred internal/external memory is not available, the allocator will try the other type of memory.

 如果某次内存分配偏向于片外存储器，您也可以使用 :ref:`CONFIG_SPIRAM_MALLOC_ALWAYSINTERNAL` 设置分配空间的大小阈值，控制分配结果：
 
-- 如果分配的空间小于阈值，分配程序将首先选择内部存储器。
-- 如果分配的空间等于或大于阈值，分配程序将首先选择外部存储器。
+- 如果分配的空间小于或等于阈值，分配程序将首先选择内部存储器。
+- 如果分配的空间大于阈值，分配程序将首先选择外部存储器。
 
 如果优先考虑的内部或外部存储器中没有可用的存储块，分配程序则会选择其他类型存储。
