A quick Google search for “2.5D 3D IC” returns 669,000 results, so it’s a popular topic for the semiconductor industry, and there are plenty of decisions to make, like whether to use an organic substrate or silicon interposer for interconnect of heterogenous semiconductor die. Design teams using 2.5D and … Read More
3D IC technology development started many years ago well before the slowing down of Moore’s law benefits became a topic of discussion. The technology was originally leveraged for stacking functional blocks with high-bandwidth buses between them. Memory manufacturers and other IDMs were the ones to typically leverage this … Read More
My first exposure to seeing multiple die inside of a single package in order to get greater storage was way back in 1978 at Intel, when they combined two 4K bit DRAM die in one package, creating an 8K DRAM chip, called the 2109. Even Apple used two 16K bit DRAM chips from Mostek to form a 32K bit DRAM, included in the Apple III computer, circa… Read More
