Lambda memory billing

Hello,

I've been researching for a while exactly how the billing of memory works but I could not find a solid answer to my question.

Here is my case: A function takes 1s to execute, has maximum allocated memory of 512mb but uses only 256mb of memory.

Will I be billed for the actual usage of memory (256mb) or the maximum allocated memory (512mb)?
