A high-speed mobile communications technology whose maximum speed is 20Gbps. semiconductor memory gains its name from the fact that, unlike DRAM, the data does not need to be refreshed dynamically. It used a cathode ray tube to store bits as dots on the screen's surface. By transferring data alternately from one set of addresses, and then the other, SDRAM cuts down on the delays associated with non-synchronous RAM, which must close one address bank before opening the next. Memory that records data, where recorded data can be read or modified. This is typically applied to an erase pin on the chip. Volatile memory loses its stored data when the power to the memory chip is turned off. Definition:- Semiconductor memory is the main memory element of a microcomputer-based system and is used to store program and data. This is normally achieved by exposing the silicon to ultraviolet light. For decades, the U.S. has been a leader in the semiconductor industry, controlling 48 percent (or $193 billion) of the market share in terms of revenue as of 2020. A typical SRAM uses 6 MOSFETs to store each memory bit although additional transistors may become necessary at smaller nodes. Also known as integrated-circuit memory, large-scale integrated memory, memory chip, semiconductor storage, transistor memory. This is normally achieved by exposing the silicon to ultraviolet light. This form of semiconductor memory can run at faster speeds than conventional DRAM. However it can be faster and less expensive than non-volatile memory. For instance, SRAM is faster than DRAM, and is well suited to high-speed caching. Nvidia and Advanced Micro Devices (AMD) were also restricted from supplying high-end graphics processors and A.I. [14] SRAM became an alternative to magnetic-core memory, but required six MOS transistors for each bit of data. A ROM(read-only memory) is a sort of semiconductor memory technology applied where the data is written once and then not changed. 1974 Intel receives a U.S. patent for a memory system for a multi chip, 1984 Apple Computers releases the Macintosh, What is semiconductor?
