The types of chips produced by semiconductor companies can be ca▨tegorized in two ways. Usually, chips are categorized in terms of their functionality. However, they are sometimes divided into types acꩵcording to the integrated circuits (ICs) used.

When looked at according to functionality, the four main categories of 澳洲幸运5官方开奖结果体彩网:semiconductors are memory chips, microprocessors, standard chips, and complexജ systems-on-a-chip (SoCs). When organized by types of integrated circuitry, the three types of chips are digital, analog, and mixed.

Memory Chips

From the perspective of functionality, 澳洲幸运5官方开奖结果体彩网:semiconductor memory chips store data and programs on c🅷omputers and data storage devices.

Random-access memory (RAM) chips provide temporary workspaces, whereas flash memory chips hold information permanently u♌nless erased. Read-only memory (ROM) and programmable read-only memory (PROM) chips cannot be modified. In contrast, erasable programmable read-only memory (EPROM) and electrically erasable read-only memory (EEPROM) chips can be changed.

Microprocessors

Microprocessors contain one or more central processing units (CPUs). Computer servers, personal computers (PCs), tablets, and s🥃martphones may each have multipl💫e CPUs.

The 32- and 64-bit microprocessors in PCs and serve🌸rs today are based on x86, POWER, and SPARC chip architectures, first developed decades ago. On the other hand, mobile devices like smartphones typically use an ARM chip architecture. Less powerful 8-, 16- and 24-bit micropr🐻ocessors (called microcontrollers) turn up in products such as toys and vehicles.

Graphic Processing Units (GPUs)

Technically a type of microprocessor, 澳洲幸运5官方开奖结果体彩网:Graphics Processing Unit (GPU) is capable of rendering graphics for display on an electro🍌nic device. The GPU was introduced to the wider market in 1999 and is best known for its use in providing the smooth gr𒉰aphics that consumers expect in modern videos and games.

Before the arrival of GPUs in the late 1990s, graphic rendering was handled by the Central Processing Unit (CPU). When used in conjunction with a CPU, a GPU can increase computer performance by taking on some computationally-intensive functions, such as rendering, from the CPU. This accelerates how quickly applications can process since 🔯the GPU can perform many calculations simultaneously. This shift also allowed for the development of more advanced and resource-intensive software and activities such as cryptocurrency mining.

Commodity ICs

Commodity integrated circuits (CICs), are simple chips used for performing repetitive processing routines. Produced in large batches, these chips are generally used in single-purpose appliances such as barcode scanners. Characterized by razor-thin margins, the commodity IC market is dominated by large Asian semiconductor makers. If an IC is made for a specific purpose, it is called an ASIC, or application-specific integrated chip. For example, bitcoin mining today is accomplished with ASICs that only do that one function: mining. Field-programmable gate arrays (FPGA chips) are another type of commoditized IC that canဣ be customized⛄ to a manufacturer's specifications.

The SoC (system on a chip) is among the newest type of chip and the most welcoming to new manufacturers. In the SoC, all of the electronic components needed for an entire system are built into a single chip. The capabilities of a SoC are more extensive than those of a microcontroller chip, which generally combines the CPU with RAM, ROM, and 澳洲幸运5官方开奖结果体彩网:input/output (I/O). In a smartphone, the SoC may also integrate graphics, camera, and audio and video prℱocessing. Adding a management chip and a radio chip results in a three-chip solution.

Taking the ot✅her approach to categorizing chips, most computer processors currently use digital circui🐻ts. These circuits usually combine transistors and logic gates. Sometimes, microcontrollers are added. Digital circuits use digital, discrete signals that are generally based on a binary scheme. Two different voltages are assigned, each representing a different logical value.

Analog Chips

Analog chips have been mos🃏tly, but not entirely, replaced by digital chips. Power supply chips are usually analog chips. Analog chips are still required for wideband signals, and they are still used as sensors. In analog chips, voltage and current vary continuously at specified points in the circuit.

An analog chip typically includes a transistor along with passive elements such as an in🍷ductor, capacitors, and resistors. Analog chips are more prone to noise, or small variations in voltage, which can cause errors.

Mixed Circuit Semiconductors

Mixed circuit s𝐆emiconductors are typically digital chips with added technology for working with both analog and digital circuits. A microcontroller might include an analog-to-digital converter (ADC) for connecting to an analog chip, such as a temperature sensor, for example.

A digital-to-analog converter (DꦬAC), conversely, can allow a microcontroller to produce anal🤡og voltages for making sounds through analog devices.

The Bottom Line

The semiconductors industry has been lucrative and dynamic, in𝐆novating across several lines of the computing and electronics market. Knowing what type of semiconductor a company makes, say CPUs vs. GPUs, vs ASICs,꧟ can help you make better and more informed investment decisions within the industry group.
