Rockwell Tri-port Memory Chip Silicon Wafer, R8040 - 4", 100mm, Triport, T-1

About this Artwork: About the Rockwell R8040 Tri-Port Memory ChipThe R8040 Tri-Port Memory chip was designed to support Rockwell's T-1 communication chips: the R8050, R8060, and R8070. The R8040 is designed to function as an assembly point and temporary storage area for 8-bit T-1 data. It provides 64 8-bit locations of on-chip random access memory, which can be accessed randomly or sequentially. Referring to the narrative on the back of the artwork, to the top-right is an image of a single R8040 chip. The chip is divided into upper and lower memory banks. The artwork was made from the area of the chip in the red rectangle. This area includes several memory cells and the interconnect logic that runs through the center between the two banks. Inside the red rectangle is a much smaller yellow rectangle. This bug-like pattern repeats throughout the memory banks. The lower picture to the right is from the artwork and is the area inside the yellow rectangle. This structure is four bits of mem
