BlackBerry device memory

BlackBerry® devices include the following types of memory:




The BlackBerry operating system and all application modules are stored persistently in flash memory. When a BlackBerry device user turns on the BlackBerry device, the core operating system and the BlackBerry® Java Application modules use approximately 10 MB to 15 MB of flash memory, depending on the version. Flash memory can store the BlackBerry device user's email messages, organizer data, and other personal information, as well as the data that a BlackBerry Java Application stores in memory.


SRAM controls the transient data objects and runtime processes.

microSD expandible memory card

The microSD card stores media files, documents, and persistent data from a BlackBerry Java Application.
