Due at the start of class, Wednesday, October 14.

Turn in circuit diagrams for the memory circuits described below. Please turn in a hard copy (hand-drawn is fine). For the last three questions, consider the error detection and correction scheme discussed in class. We will discuss these during class, so no late submissions are accepted.

1. Implement a 1 ×4 memory using D-type flip flops as building blocks.
2. Implement a 4 ×4 memory using the 1 ×4 memory from the previous question as building blocks.
