When **S** is `ON`, **0** will mirror whatever state **I** is in. However if you turn **S** `OFF`, **O** will remain in whatever state it was when **S** was turned `OFF`. You can toggle **I** as much as you like, **O** will remain in its previous state. Hence creating a memory store of the past value of **I**. When **S** is `ON`, **0** will mirror whatever state **I** is in. However if you turn **S** `OFF`, **O** will remain in whatever state it was when **S** was turned `OFF`.

The specific reason for this is that, if **S** is `OFF`, both **A** and **B** are `ON` The specific reason for this is that, if **S** is `OFF`, both **A** and **B** are `ON` since `ON + OFF` at A equals `ON` and `
