Unidentified chip

This is a chip I opened prior to me realizing I should record what the package looks like before destroying it. I do not know what this chip is, but it looks pretty cool so I've decided to upload it.

 

There are five repeating structures on the left side and three on the right, but I do not have any documentation to know what they are.
