3D transistors, 3D chips, and 2.5D

“From the ultra-small 3D transistors described in papers at this month’s International Electron Devices Meeting (IEDM) in Washington, D.C., to the 2.5D and 3D multichip structures described at the 3D Architectures for Semiconductor Integration and Packaging (ASIP) conference held in Burlingame, Calif., designers are finding more ways to pack more transistors on a chip and to pack more functions into a limited area on a printed-circuit board … Robert Patti, the CTO of Tezzaron Semiconductor described a combination of dis-integration and then integration to create a high-density and high-performance memory stack (See “Advances in DRAM and non-volatile memories keep upping system performance”, Aug. 26, 2013). The architecture of the memory array provides 256 independent channels, each containing 256 Mbits of storage and capable of transferring data at 64 Gbits/s with a latency of just 9 ns”
