Relevant discussion may be found on the talk page. This subsection needs additional citations for verification. Įstimates of the total numbers of transistors manufactured: Ionic transistor chips ("water-based" analog limited processor), have up to hundreds of such transistors. The first carbon nanotube computer had 178 transistors and was a 1-bit one-instruction set computer, while a later one is 16-bit (its instruction set is 32-bit RISC-V though). Early experimental solid-state computers had as few as 130 transistors but used large amounts of diode logic. In terms of computer systems that consist of numerous integrated circuits, the supercomputer with the highest transistor count as of 2016 was the Chinese-designed Sunway TaihuLight, which has for all CPUs/nodes combined "about 400 trillion transistors in the processing part of the hardware" and "the DRAM includes about 12 quadrillion transistors, and that's about 97 percent of all the transistors." To compare, the smallest computer, as of 2018 dwarfed by a grain of rice, had of the order of 100,000 transistors. Wafer-scale design of 84 exposed fields (dies)ĭual-die SoC entire M2 Ultra is a multi-chip module Stacked package of sixteen 232-layer 3D NAND dies The highest transistor count in a consumer microprocessor is 134 billion transistors, in Apple's ARM-based dual-die M2 Ultra system on a chip, which is fabricated using TSMC's 5 nm semiconductor manufacturing process. Īs of 2023 highest transistor count GPU is AMD's MI300X, built on TSMC's N5 process and totalling 153 billion MOSFETs. It has 2.6 trillion MOSFETs in 84 exposed fields (dies) on a wafer, manufactured using TSMC's 7 nm FinFET process. The highest transistor count in a single chip processor is that of the deep learning processor Wafer Scale Engine 2 by Cerebras. However, being directly proportional to the area of a chip, transistor count does not represent how advanced the corresponding manufacturing technology is: a better indication of this is the transistor density (the ratio of a chip's transistor count to its area).Īs of 2023, the highest transistor count in flash memory was Micron's 2 terabyte ( 3D-stacked) 16-die, 232-layer V-NAND flash memory chip, with 5.3 trillion floating-gate MOSFETs ( 3 bits per transistor). The rate at which MOS transistor counts have increased generally follows Moore's law, which observed that the transistor count doubles approximately every two years. It is the most common measure of integrated circuit complexity (although the majority of transistors in modern microprocessors are contained in the cache memories, which consist mostly of the same memory cell circuits replicated many times). ( PNP's "missed the boat" for popular use in discrete logic implementation a few decades ago because of cost, so NPNs became the traditional choice, enforced by decades of examples in text books, magazine articles, on-line tutorials, etc.The transistor count is the number of transistors in an electronic device (typically on a single substrate or "chip"). Or, with constructing logic functions from discrete transistors in which case NPNs are the type most frequently utilized. You are likely most familiar with TTL-like logic families which utilize on-chip NPN transistors. It depends on the fundamental switching element utilizied. So, it is not universally true that NOR & NAND functions require two transistors, or three for AND & OR. In others, the AND or NAND function would require the minimum number of elements to implement. the Diode OR function Phil Frost provided). In some of these systems the OR or NOR function are "natural" and require the least number of elements to implement (e.g. However, if the fundamental element is changed from an NPN transistor to a PNP transistor, or NMOS transistor, or PMOS transistor, or CMOS (pairs of NMOS & PMOS transistors), or even diodes, you will find that a different number of those fundamental elements will be needed to form the basic logic functions. Ubuntu_noob has shown the three functions (NAND, NOT, NOR ) created with NPN-only devices. Your question appears to be premised on the use of an NPN transistor as the fundamental switching element used to construct the logic gate or function.
