What is RAM Boost?

Published in Memory Management 3 mins read

RAM boost is a technology found on some smartphones and devices designed to improve performance when the physical RAM is nearing its capacity. It essentially provides a temporary overflow area for data.

When your device is running many apps simultaneously, the physical Random Access Memory (RAM) can become full. This can lead to slowdowns as the system struggles to manage active processes.

How RAM Boost Works

According to information on this topic, when your smartphone's physical RAM is maxed out due to numerous apps running at once, RAM Booster watches and kicks in. It allocates a portion of the device's internal storage to act as an overflow for the RAM.

Think of your physical RAM as your main desk space – it's very fast but limited in size. When your desk gets too cluttered with active tasks, RAM Boost is like having a quick-access filing cabinet nearby. It temporarily moves less-critical data or processes that don't need immediate access from the fast 'desk' (RAM) to this allocated space on the slower 'filing cabinet' (internal storage). This frees up space on the physical RAM for truly active tasks.

Benefits of RAM Boost

Utilizing RAM boost can offer several advantages:

  • Smoother Multitasking: By offloading less active data, it helps the system keep more apps open in the background without significant slowdowns.
  • Improved App Launch Times: When freed-up RAM is available, new apps can potentially launch faster.
  • Reduced Lag: Can help mitigate performance drops when pushing your device's memory limits.

Understanding the Trade-offs

While beneficial, it's important to note that internal storage (like UFS or eMMC) is significantly slower than physical RAM. Moving data back and forth between RAM and this allocated storage takes more time than simply accessing data already in RAM. Therefore, RAM boost is a performance helper or extender, not a direct replacement for having sufficient physical RAM.

RAM vs. RAM Boost (Allocated Storage)

Here's a simple comparison:

Feature Physical RAM RAM Boost (Allocated Storage)
Speed Very Fast Noticeably Slower
Capacity Fixed by Hardware Variable (User Selectable)
Source Dedicated Memory Chips Device's Internal Storage
Primary Role Active Data & Processes Overflow/Temporary Storage
Cost More Expensive per GB Less Expensive per GB

Practical Insight: Virtual RAM

RAM boost is often marketed under different names by various manufacturers, commonly referred to as virtual RAM or memory extension. Many modern smartphones allow users to select how much internal storage they want to allocate for this feature, typically ranging from 1GB up to several gigabytes depending on the device's total storage capacity and software implementation.
