/**
 * A RAM event is defined as anything that causes a read or write to the

 * address fetch (indirect addressing) as well as direct or indexed operator
 * addressing modes.
 *
 * It is also possible to track if the read is an opcode read, indicating that
 * the CPU is executing the given memory location at that moment.
