The role of RAM and ROM in a smartphone is very important as it supports performance capabilities.
RAM stands for Random Access Memory, which is used for temporary storage media. Support plays a role in supporting smartphone performance, so if the phone has more RAM, the phone's performance will be better in performing multi-tasking tasks, opening applications, and other work.
ROM stands for Read-Only Memory, which is installed on computers and smartphones. Storing files in the ROM is permanent. All the data that has been stored in ROM will not be easily lost. Its nature is inversely proportional to the function of RAM.
Saving data to ROM can be done in a certain way, for example, flashing. All the data that has been stored in ROM is "Read" and easy to read.
The programs that have been stored in ROM have been determined to function for the main system as has been determined by the vendor in the form of operating system software and applications.
So it can be concluded that ROM is actually a hardware device in the form of an IC chip and has a different generation.
ROM already has various variants that have been widely used, either installed on cellphones or other devices. has the same function but results in different performance and applications depending on usage and type.
It is the first type of memory from ROM that contains a data set of instructions that have been programmed by the vendor. The abbreviation for Mask Read-Only Memory has a low price.
EEPROM stands for Electrically Erasable and Programmable Read-Only Memory with similar characteristics to EPROM. Programs in the EEPROM can be erased and reprogrammed up to 10,000 times. The uninstall process and programs only take about 4 to 10 milliseconds.
Users can program as a whole or selectively.
Flash Memory
Is it a more modern type of memory compared to EEPROM? Its nature can be written and reprogrammed at a faster rate.
Flash memory can be erased and reprogrammed more than once a million times. With the features of durability and memory durability, NAND Flash replaces magnets in several applications, such as USB flash drives.
In general, everything is not the same as RAM; the characteristics and functions are different.
The phone's RAM type order The most basic difference between RAM and ROM is the nature of the two. If ROM functions to store mobile phone data files permanently, this is inversely proportional to the function of RAM.
RAM is memory that stores volatile process data. All system process data will be automatically stored in RAM temporarily, making it easier for the processor to repeat reads. Smartphone performance in multi-tasking and opening applications is much influenced by RAM, so that if the capacity is bigger, the phone has a better processing speed.
There have been many versions of RAM released, and the more recent versions generally have better capabilities.
RAM Type Configuration in a Smartphone
Smartphones are smaller than computers. This also means every component in it is designed at a small size, including RAM. Currently, there are five types of RAM that have been released to the market and are widely used by smartphone devices.
1. The first smartphone had LPDDR RAM.
It has been installed on various old variants of cellphones, for example, from Samsung, Motorola, and other brands.Its capabilities are still limited, so that the use of this version is already quite behind the others.
2. LPDDR2.
is a second generation RAM that differs from the RAM found in the first smartphone.This type has a clock speed of 266MHz faster than the previous version. Not only is the speed of RAM LPDDR2 improved, it also has improvements in power consumption. This type of RAM can be found on Asus, Samsung, and so on.
3. LPDDR3 RAM
LPDDR3 is a generation that is better than its predecessors. Having better bandwidth data transfer speeds allows for more agile device performance. LPDDR3 has a prefetch architecture and consists of one 32-bit channel. It has been discovered in many Xiaomi MiA1, Samsung S5, and other devices.
4. RAM LPDDR4.
with a clock speed of up to 4,266 Mbps was introduced in 2012.It is rated to be 1.2 times faster than the LPDDR3 in doing work. In addition, its ability to consume more efficient power reduces power by up to 37%. Some devices with this type of RAM include the Xiaomi Mi3, the OnePlus 2, and others.
5. LPDDR4X RAM
The next generation is LPDDR4X, which is 15% faster in processing data than the previous generation. In doing the same work as before, but in terms of power consumption, it is more efficient.
6. The most recent and best cell phone RAM is LPDDR5.
Its capabilities support all modern computing jobs. LPDDR5 is the ideal type of RAM that supports smartphones with 5G internet network capabilities, Artificial Intelligence (AI), and gaming needs with more optimal performance.
The LPDDR5 type of RAM has a relatively higher price, for which it can only be found on flagship smartphones such as the Samsung Note 10 5G, Samsung Galaxy S20+/S20, Asus ROG, Xiaomi Black Shark, and so on. So far, we've learned about the various types of RAM and ROM, as well as a basic overview of the differences.
The Difference Between RAM and ROM.
Although both have the basic function as a storage medium, they can be distinguished based on the task as follows:
The ROM works to store data permanently, while the RAM is only temporary. Any process data stored in RAM will be lost automatically if the device is turned off or rebooted.
Meanwhile, the data in ROM is not affected by electric current. That's the difference between ROM and RAM, also the development of the type of generation that has been released.
