Key Things to Know: As monolithic chips become ever larger and more complex, monolithic manufacturers face lower yields and increased costs. It is now possible to “mix and match” pre-manufactured, monolithic chiplets from which to build the equivalent of a system on a chip (SOC). They can save money by utilizing an inexpensive, low-power I/O chiplet if I/O needs are sporadic.
