RAM and ROM

The memory of our smartphone is one of the key points when buying a new one. But there are two types of memory: RAM (immediate) and ROM (internal).

Differences between the RAM and ROM

The RAM memory is of smaller capacity and helps the processor to have all the information it needs for its calculations.

The ROM or internal memory is a long-term memory where we can install the operating system, applications and save our files. Let's look at them in detail.

RAM

We have the definition of RAM memory when decomposing its own acronym: Random Access Memory.

In Spanish it means: random access memory, since it can be read and written in any position without having to wait for a queue of processes.

This speeds up the data capture because, unlike ROM or microSD memory, it is very easy to access the physical place where the data is stored.

RAM memory features

In the RAM memory is loaded everything necessary for the device to work, ie the operating system and applications that we are using at the time or that operate in the background.

The RAM memory is where the processor takes directly the information it needs. The RAM memory and processor are therefore contained in a single (indivisible) module soldered directly to the motherboard.

The more RAM a smartphone has, the better it generally performs and is usually faster, although this also depends on the type of memory and the quality of its construction.

RAM only works when the device is turned on. That is to say, it is not able to store information once we turn off the device.

This is the reason why when we turn on the device we need to wait a little until the whole system is loaded into RAM.

RAM memory types

There are many types of RAM and it can be too technical to talk about all of them. In general the main differences are in reading speed and energy consumption.

The first RAM memories arrived in the 60's and with each generation they have had more capacity, have been much faster and have consumed less energy.

Currently the most powerful smartphones on the market incorporate a RAM memory of 6 and 8 GB.

The world of mobile telephony uses a very special type called LPDDR that consume very little energy, heat very little, are very small and of course are not economical at all. Currently the most widespread are LPDDR2, LPDDR3 and LPDDR4.

These are the last three generations of this type of memory for mobile devices. The main difference is that with each generation the transmission speed has doubled.

The first LPDDR5 RAM is expected to hit the market in late 2018 with the release of the Samsung Galaxy S10.

With the change from LPDDR3 to LPDDR4 we saw how the speed of the RAM doubled, so with this new evolution we can expect big improvements.
