How to write and read the data from RAM

Hi friends,

I am using AT91SAM7SE512 micro controller.
I am working in a safety project.
I want to test the Internal RAM data,
before starting the process i want to check(self test)the Internal RAM memory.

For this i am following the "GALPAT test"(given by EN61508 standard).

My doubt is "how to read and write the RAM memory?"

I have go through the RAM_function and some other examples.But i couldn't get the clear idea.

Please help me on this topic.

With regards,

Here's a very simple RAM read-write sequence:

{

 volatile int a;
 volatile int b;

 a = b;    // here is where all the magic happen
 while(1); // "He is dead Jim, He is dead!"
}
