Bit Chip

1. Bit Chip

The Bit chip stores a single bit of data. It acts like a 1-bit register that can either maintain its previous state or update based on the load input signal.

2. Truth Table

in	load	out	Notes
0	0	?	Keeps previous value (no update)
1	0	?	Keeps previous value (no update)
0	1	0	Updates stored value to 0
1	1	1	Updates stored value to 1

3. Implementation (Logisim)

Representation of the Bit Chip using a DFF and Mux to control updating.

4. Implementation (HDL)

The Bit chip uses a D flip-flop to store state, and a Mux to decide whether to load a new input or keep the current one.

CHIP Bit {
    IN in, load;
    OUT out;

    PARTS:
    Mux(a=out, b=in, sel=load, out=muxOut);
    DFF(in=muxOut, out=out);
}
