 /**
- * Memory of 8 registers, each 16-bit wide.  
- * The chip facilitates read and write operations, as follows:
- *     Read:  out(t) = RAM8[address(t)](t)
- *     Write: If load(t-1) then RAM8[address(t-1)](t) = in(t-1)
- * In words: the chip always outputs the value stored at the memory 
- * location specified by address. If load == 1, the in value is loaded 
- * into the memory location specified by address.  This value becomes 
- * available through the out output starting from the next time step.
+ * Memory of eight 16-bit registers.
+ * If load is asserted, the value of the register selected by
+ * address is set to in; Otherwise, the value does not change.
+ * The value of the selected register is emitted by out.
