/**
* Memory of 64 registers, each 16-bit wide.
* The chip facilitates read and write operations, as follows:
* Read: out(t) = RAM64[address(t)](t)
* Write: If load(t-1) then RAM64[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.
