+3  A: 

Memory Management

It's all about Java Virtual Machine which is a part of OS:

The BlackBerry® Java® Virtual Machine manages memory usage on the BlackBerry device. The BlackBerry JVM allocates memory, performs garbage collection, and automatically swaps data between SRAM and flash memory. The BlackBerry JVM must also share available memory between the BlackBerry device applications and the BlackBerry® Java Application. The memory capabilities represent the total amount of available memory, which is larger than the available working memory when all of the applications and associated application data exist on the BlackBerry device.
