What kinds of memory does an Android device have? What kind/types of memory (or data storage devices) does and android device have, and what information is stored in that type of memory?

I know of:


Internal memory
RAM Memory
ROM Memory
Storage card / SD/Card
Android devices are very similar to computers, they consist of a BIOS (Basic Input Output System), an OS (Operating System) and then Applications and Data.


The BIOS would be stored in EEPROM (Electrically Erasable Programmable Read Only Memory), or rather a sub-type called Flash Memory. (Wikipedia)
When the BIOS loads the OS then it is moved into RAM Memory. RAM memory stores all currently running applications (including the OS). (Wikipedia)
The Operating System software, and application software are stored in storage; which is usually an internal SD card, or SD card like storage. (Wikipedia)


You can have additional storage, such as an external SD card.



So you would have


EEPROM (Flash Memory)
RAM (System Memory)
SD Card (Storage)
