Internal Memory
FLASH
The LM3S1150 microcontroller comes with 16 KB of bit-banded SRAM and 64 KB of flash memory.
The flash controller provides a user-friendly interface, making flash programming a simple task.
Flash protection can be applied to the flash memory on a 2-KB block basis.

Functional Description
This section describes the functionality of both the flash and SRAM memories.
SRAM Memory
The internal SRAM of the Stellaris
map. To reduce the number of time consuming read-modify-write (RMW) operations, ARM has
introduced bit-banding technology in the Cortex-M3 processor. With a bit-band-enabled processor,
certain regions in the memory map (SRAM and peripheral space) can use address aliases to access
individual bits in a single, atomic operation.
