Every picture goes to a separate chunk of very fast memory called the buffer. The buffer then writes out to the SD card at a more leisurely pace. The camera stops taking pictures when the buffer is full and you can't take another until room for 1 more picture has been cleared.

The internal memory you are referring to is NOT the buffer. It's just extra built in flash memory space (think of it like a built in SD card) for emergency picture storage. Most DSLR cameras have NO internal flash memory but they still have large buffers for high end burst shooting.
