Galaxy Techfluencer topic for the week: Random Access Memory

RAM is an essential component that is used for the Read, Write/Modify or Execute operation. It could be an image, text file or any application. All of these are loaded to RAM before performing any operation. With RAM, operations can be done at a better speed resulting in better user experience.

Random Access Memory or RAM in a mobile phone is very important and the higher the RAM in a cell phone, the faster the mobile cell phone will operate

For best performance in mobile, computer etc. a good balance between processor, GPU and RAM is required.RAM is responsible for multitasking, the greater theRAM the more number of applications can run simultaneously. ... The processor is the brain of a device, the faster with multiple cores the better it will perform
RAM is a very fast responding memory that can be quickly erased and new data written on it. All applications to be executed on a phone is first loaded on to the RAM from the main storage memory of the phone.
The main memory of a phone is slow and it cannot execute programs on the phone fast enough. So the phones OS (android) , controls the RAM and decides on the timing of loading into the RAM of what is required in the next few milli-seconds while a phones App is being executed, and loads those programs from the slow loading memory into the fast RAM ready to execute when required. As soon as the RAM executes that part of the App, fresh memory required for the next few milliseconds are loaded on to the RAM and the old executed portions are erased from the RAM.
The RAM is made up of millions of capacitors each capable of holding one ‘bit’ of information. That means in a RAM of 1 GB there should be at least 1,000,000,000 capacitors since a Giga byte = 1000 Mega bytes. The Capacitors in the RAM lose its charge as soon as it is powered off, so all of the Memory in a RAM can be removed and new memory loaded in the RAM in a fraction of a millisecond just by switching it ‘off’ and ‘on’.
Since the memory of a RAM is very volatile and dynamic, RAM is referred to as having a ‘Volatile Memory’ and being dynamic, and often referred to as ‘Dynamic Random Access Memory’ or ‘DRAM’. The speed of the RAM is known as 'clock speed'. For cell phones the clock speeds of RAM are kept at moderate rates of 300 to 500 MHz to save on power usage. The RAM in smart phones are a type known as LPDDR2 (low-power double data rate 2nd generation) RAM. In a laptop computer faster DDR3 SDRAM (double data rate third generation synchronous dynamic random access memory) are used, but they consume much more power and so cannot be used in smartphones.

i am facing battery issues

[kichua]

yup

The RAM of my phone works quite well because i do not overload my device with a lots of app which aren't useful to me i use less graphics games so that device works properly and this prevents my device from heating up if we make sure of these points our device will run quite well and cause less problem.

Android 10 Update makes my M30s to drink the battery and ram😤

[BKJadav]

I'm slowly open

[SolomonGanji]

I don't understand why these phones are lagging even though good RAM
i am using Samsung A50S....it is very slow. sometimes it is irritating. this is my second Samsung phone. My first phone M series. i came to know that A and S series better. But I am facing same issues.
I don't know why Samsung couldn't fix this problem.. Very strange

RAM stands for Random Access Memory. It is sort of temporary memory where the files of the app opened in background get stored while the app is running. Ram takes app data from the main memory i.e., ROM which results faster transfer and manipulation of data as RAM is way faster than rom. But not all data can be stored in Ram as it can't store huge chunks of data in itself.
Similar to a microprocessor, a memory chip is an integrated circuit (IC) made of millions of transistors and capacitors. In the most common form of computer memory, dynamic random access memory (DRAM), a transistor and a capacitor are paired to create a memory cell, which represents a single bit of data. The capacitor holds the bit of information -- a 0 or a 1 (see How Bits and Bytes Work for information on bits). The transistor acts as a switch that lets the control circuitry on the memory chip read the capacitor or change its state.

­A capacitor is like a small bucket­ that is able to store electrons. To store a 1 in the memory cell, the bucket is filled with electrons. To store a 0, it is emptied. The problem with the capacitor's bucket is that it has a leak. In a matter of a few milliseconds a full bucket becomes empty. Therefore, for dynamic memory to work, either the CPU or the memory controller has to come along and recharge all of the capacitors holding a 1 before they discharge. To do this, the mem­ory controller reads the memory and then writes it right back. This refresh operation happens automatically thousands of times per

The capacitor in a dynamic RAM memory cell is like a leaky bucket. It needs to be refreshed periodically or it will discharge to 0. This refresh operation is where dynamic RAM gets its name. Dynamic RAM has to be dynamically refreshed all of the time or it forgets what it is holding. The downside of all of this refreshing is that it takes time and slows down the memory.

Ram in mobile to hold data when apps are opened..means Execute operation...higher the ram we get mobile doesn't slow down..
