I wonder if these logic densities could be converted into units of nanometers. For example 333 MTr/mm2 is 333 Tr/um2. Then there are effectively sqrt(333) transistors on a side of a square micrometer which comes out to about 1/sqrt(333) * 1000 = 55 nanometers per transistor. Way off from the 2 nanometer feature size
- watersb 5y ago> 55 nanometers per transistor. Way off from the 2 nanometer feature size. Cool. Following along here, I consider that transistors require multiple "features", and these days the more complicated transistor structure has enabled the increase in speed while lowering the power requirements. Power is also now a set of characteristics, the power needed to change transistor state, and the leakage current that remains when the transistor is not switching. Not just a simple NPN junction FET anymore. Then I think about those great microchip analyses on Ken Sheriff's blog. How very different transistor layouts show up in circuit designs. I can only imagine that modern high performance SOC design is even more complex. https://righto.com https://righto.com 55 nanometers per transistor sounds like a useful number to me.
