Let's take a closer look at a very interesting silicon wafer from Dallas Semiconductor with a hidden doodle on it.

There are some rather large chips on this silicon wafer, and there might actually be more stuff in the margins in between each chip then there are actual chips on it. It’s in these margins where the doodle lives. In order to see it thought, we need the help of a microscope.

Sitting next to some test circuits is a Tiger with the text “GEUAX DSC”.

Unfortunately, this is an unfinished wafer. The back of the wafer says DS2256, but I wasn’t able to find a datasheet for this part. To me, it looks like some type of SRAM. There is however a datasheet for the DS2257, which is a 32 Kilobyte SRAM. Since nearby Dallas Semi part numbers are usually related, it’s highly plausible the DS2256 is also an SRAM device

This wafer is loaded with interesting looking test patterns. It also has a very inspirational quote left behind by one of the designers.
