ABB XVC767AE105 3BHB007209R0105 Industrial control module uses semiconductor based integrated circuit to store information chip. Data is usually stored in metal-oxide-semiconductor (MOS) memory cells. A semiconductor memory chip may contain millions of memory cells, capacitated by tiny metal-oxide-semiconductor field-effect transistors (MOSFETs) and/or MOS.

ABB XVC767AE105 3BHB007209R0105 Industrial control modules Both unstable and non-volatile exist in various forms of semiconductor memory, the former using standard MOSFETs, the latter using floating gate MOSFETs. In modern computers, the main memory is almost entirely composed of dynamic volatile semiconductors random access memory (memory), in particular dynamic random access memory (DRAM). Since the turn of the century, a type of non-volatile floating gate semiconductor memory known as flash memory has steadily gained market share as an offline memory for home computers.

ABB XVC767AE105 3BHB007209R0105 Industrial control module Non-volatile semiconductor memory is also used for auxiliary storage in various advanced electronic devices and dedicated computers designed for them. A coated surface that uses different modes of magnetization to magnetically store information. Magnetic memory is non-volatile. Information is accessed using one or more read/write headers that can contain one or more record sensors. The read/write head covers only part of the surface, so in order to access the data, either the head or the medium or both must move relative to the other. In a modern computer, magnetic storage will take the following form
