Documentation

This class simulates RAM in a computer. It has a certain capacity and takes a certain (short) amount of time to read and write data.

IMPORTANT NOTE: currently, the simulator disregards the amount of time it takes to read something from RAM. Instead, it simply assumes N RAM accesses per CPU second (a parameter set in the config file). So most of this object is going unused at the moment.
