What is RAM?
RAM stands for Random Access Memor, which is a device’s RAM. This RAM is a form of storage that makes data accessible randomly at any time, from any point in any order.
RAM is the most common type of memory found in computers and other electronic devices.
A RAM memory card contains millions of tiny capacitors, all storing electrical charges. These loads represent bits of data. The capacitors are arranged in rows and columns, and each row is connected to a wire commonly called a bitline.
Bitlines are connected to other wires known as wordlines. Each wordline represents a line of bits, while each bitline represents a column of bits.
RAM is a volatile entity. That means it needs energy to keep the data inside the storage capacitor. If power is lost, the data is instantly lost.
There is also a non-volatile RAM called NVRAM. This is a type of RAM that does not require power to keep data in the storage capacitor. NVRAM is used in applications where data must be stored for a long time, even when power is off.
An example of this NVRAM is flash memory. This is commonly used in USB drives and digital cameras.
