Posted 27 Sep 2012 Hi friends, whenever i read specifications of a specific CPU i always confused by work memory and load memory. Can anybody explain these two Work memory and Load memory in easy words? Share this post Link to post Share on other sites

Load memory is ROM and RAM that that holds the program. That's my interpretation anyway. Edited 28 Sep 2012 by IamJon Share this post Link to post Share on other sites
