advantages and disadvantages of serial processing operating system

But ROM, including flash memory, works by adding a second gate, known as the “floating gate,” to each cell. Volatile memory like random access memory (RAM) returns all the gates to the 0 state when the power source turns off, thus erasing all stored data.

The transistor controls the current’s path of by acting as an on-off switch, or a gate.Īn “on” transistor allows the flow of electrons across the cell, which stores a 1 in binary code.Īn “off” transistor blocks electrons and stores a 0. Here’s the process:Ĭurrent flows through the transistor between each cell’s source (electric input) and drain (electric output). Rather than use the traditional electromechanical method, flash memory uses electrical circuits to log data. How Does Flash Memory Work?įlash memory comes built into solid-state chips, and each chip houses an array of flash memory cells.

Although technically a type of read-only memory (ROM), flash memory is distinct from conventional ROM in that you can edit it as well as read it. Flash memory, or flash storage, is non-volatile, which means it remains viable even without an active power source. Flash memory is a type of erasable read-only memory (EEPROM) that clears and rewrites data in chunks for fast, energy-efficient access and rewriting.
