What is RAM?
Random Access Memory (RAM) is a form of data storage that can be accessed randomly at any time, in any order, and from any point. RAM is the most common type of memory found in computers and other electronic devices, such as printers.
More About RAM
A RAM chip contains millions of tiny capacitors that store electrical charges. These charges represent bits of data. The capacitors are arranged in rows and columns, and each row is connected to a wire called a bitline.
The bitlines are connected to other wires called wordlines. Each wordline represents a row of bits, and each bitline represents a column of bits.
RAM is volatile, meaning it requires power to maintain the data in the storage capacitor. When the power is removed, the data is lost.
Non-volatile RAM (NVRAM) is a type of RAM that does not require power to maintain the data in the storage capacitor. NVRAM is used in applications where data must be stored for long periods of time, even when the power is turned off. One example of NVRAM is flash memory, which is commonly used in USB drives and digital cameras.
