Introduction to Onboard RAM
Onboard RAM, also known as embedded RAM, is a type of random access memory that is built into the main circuit board of a device. This means that the memory is not installed as a separate module, like a RAM stick in a computer, but is instead integrated into the device’s motherboard or system-on-chip (SoC). The primary function of onboard RAM is to provide a fast and efficient way for the device to access and store data temporarily while it is being processed.
Types of Onboard RAM
There are several types of onboard RAM, each with its own unique characteristics and applications. Some of the most common types include:
Onboard RAM can be classified based on its volatility, which refers to whether the data is retained when the power is turned off. The two main types are volatile and non-volatile onboard RAM. Volatile onboard RAM, such as SRAM (Static RAM) and DRAM (Dynamic RAM), loses its data when the power is turned off, while non-volatile onboard RAM, such as flash memory, retains its data even when the power is off.
Volatile Onboard RAM
Volatile onboard RAM is the most common type of onboard memory. It is used in a wide range of applications, from computers and smartphones to embedded systems and IoT devices. Volatile onboard RAM is fast and efficient, but it requires constant power to maintain its data. If the power is turned off, the data is lost.
Non-Volatile Onboard RAM
Non-volatile onboard RAM, on the other hand, retains its data even when the power is turned off. This type of memory is commonly used in devices that require persistent storage, such as solid-state drives (SSDs) and flash memory cards. Non-volatile onboard RAM is slower than volatile onboard RAM but provides a reliable way to store data long-term.
Advantages of Onboard RAM
Onboard RAM offers several advantages over external RAM. Some of the key benefits include:
- Faster Performance: Onboard RAM is typically faster than external RAM because it is integrated directly into the device’s circuit board. This reduces the time it takes for the device to access and store data, resulting in improved performance.
