BIOS, in computing, stands for basic input/output system. BIOS refers to the software code run by a computer when first powered on. The primary function of BIOS is to prepare the machine so other software programs stored on various media (such as hard drives, floppies, and CDs) can load, execute, and assume control of the […]

An EPROM, or erasable programmable read-only memory, is a type of computer memory chip that retains its data when its power supply is switched off. In other words, it is non-volatile. It is an array of floating gate transistors individually programmed by an electronic device that supplies higher voltages than those normally used in electronic […]

An EEPROM (also called an E2PROM) or Electrically-Erasable Programmable Read-Only Memory, is a non-volatile storage chip used in computers and other devices (such as USB flash drives, in its flash memory version).
Operation
The EEPROM operates in three phases: OP-Code Phase, Address Phase and Data Phase. Each EEPROM device has its own set of OP-Code instructions to […]
