A chip that uses semiconductors to store information based on integrated circuits. Data is usually stored in metal-oxide-semiconductor (MOS) memory cells. A semiconductor memory chip may contain millions of memory cells, which are composed of tiny metal oxide semiconductor field effect transistors (MOSFETs) and/or MOS capacitors. There are many forms of semiconductor memories, both of which are unstable and nonvolatile. The former uses standard MOSFETs and the latter uses floating-gate MOSFETs. In modern computers, the main memory is almost entirely composed of dynamic volatile semiconductors, random access memory (RAM), especially dynamic random access memory (DRAM). Since the turn of the century, a nonvolatile floating gate semiconductor memory called flash memory has steadily gained market share as an off-line memory for home computers. Non-volatile semiconductor memories are also used for auxiliary storage in various advanced electronic devices and special computers designed for them. Using different modes to magnetize on a coating surface that magnetically stores information. Magnetic memory is non-volatile. Information is accessed using one or more read/write heads, which may include one or more recording sensors. The read/write head covers only a part of the surface, so in order to access data, the head or the medium or both must move relative to the other. In modern computers, magnetic storage will take the following forms.

Set the data register and buffer logic to adapt to the speed difference between CPU and peripherals. The interface usually consists of some registers or RAM chips. If the chips are large enough, batch data transmission can be realized. Coordination: It can coordinate the differences in information types and levels between CPU and peripherals, such as level shift drivers, digital/analog or analog/digital converters, etc.

Examples of hardware acceleration include the acceleration function in Bit blit Graphics Processing Unit (GPU), the use of memristors to accelerate neural networks and regular expression hardware to accelerate spam control in the computer network server industry in order to prevent regular expression denial of service (ReDoS) attacks. [181] The hardware that performs acceleration may be a part of a general-purpose CPU, or it may be a separate unit called a hardware accelerator, although they are usually referred to as more specific terms, such as a 3D accelerator or a cryptographic accelerator.
