It is a multiple-step sequence of photolithographic and … It is a special type of memory that is optimized for performing searches through data, as opposed to providing a simple direct access to the data based on the address. Since the turn of the century, a type of non-volatile floating-gate semiconductor memory known as flash memory has steadily gained share as off-line storage for home computers. When an impurity is added into the pure semiconductor, then its charge carrier gets increases and the semiconductor is known as an extrinsic semiconductor. Semiconductor Memory – RAM (93): Also known as main memory or primary storage; type of memory that temporarily holds data and instructions needed shortly by the CPU. CPU … It is the working memory of the computer. Also known as FeRAM. What is Flash Memory? Article Recommended: Semiconductor Materials:Types, Properties and Production Process. An N-type semiconductor carries current mainly in the form of negatively-charged electrons, in a manner similar to the conduction of current in a wire. Memory). Also known as FeRAM. Non-volatile semiconductor memory is also used for secondary storage in various advanced electronic devices and specialized computers that are … Our leading edge products include low cost SPI NOR FLASH,low density NAND FLASH and MCUs.Zbit has already established strategic relationship with … FLASH memory, also known as flash memory, combines the advantages of ROM and RAM, not only with electronically erasable programmable (EEPROM) performance, but also does not power off data and can quickly read data (NVRAM advantage), U disk This memory is used in MP3.
