How to classify the ROM in your smartphone? The internal storage medium is Flash memory which is soldered on to the PCB, so ROM is also called Flash. ROM is generally described as " eMMC" (Embedded Multi-Media Card), a new kind of storage technology.

It will not disappear along with the power-off phone. It means the ROM static space, only for storing data. Read Only Memory means you can read the memory only. The part of the memory used by GPU is not displayed – this is the same situation with computers.Īs with computers, when a smartphone is running, the GPU uses up part of memory that's why the available memory is less than the memory displayed in the settings. You may think you were cheated, but you were not.Īs a kind of smart hardware, the GPU (Graphics Processing Unit) also needs memory support, so it's not cheating by advertising it as 4GB RAM. Why is the actual memory less than the indicated RAM? After buying a 4GB RAM Android smartphone, people will find that the memory is only slightly more than 3GB and the actual available memory is maybe just 2GB. The 2GB, 3GB, 4GB all refer to RAM, or as we usually say, memory. In current phone configurations, you can see combinations like 2GB+16GB, 3GB+32GB, 4GB+64GB etc.
