Data is stored and read many times to and from this type of memory. Most types of semiconductor memory have the property of random access,[4] which means that it takes the same amount of time to access any memory location, so data can be efficiently accessed in any random order. [5] This contrasts with data storage media such as hard disks and CDs which read and write data consecutively and therefore the data can only be accessed in the same sequence it was written. This is typically applied to an erase pin on the chip. DepositionA process wherein a thin film is applied to a wafer surface to impart electrical characteristics. To enable this to happen there is a circular window in the package of the EPROM to enable the light to reach the silicon of the chip. While every effort has been made to follow citation style rules, there may be some discrepancies. As semiconductor devices, memory chips are composed of transistors and capacitors: the capacitors serve to store two binary logic bits (0 or 1), while transistors allow reading and writing of data to the capacitors. Data can be written to it and it can be erased using an electrical voltage. Three companiesIntel, Samsung and TSMCaccount for most of this investment.
