**Question 22**

Find the chip capacity for an EPROM with 13 address lines and 8 data lines.

**Selected Answer:** 8192

---

### Explanation:

When determining the chip capacity, an EPROM's (Erasable Programmable Read-Only Memory) capacity is calculated by multiplying the number of addressable locations by the data width (number of data lines).

- **Address Lines:** 13 address lines mean 2^13 possible addresses. This is because each line can be either 0 or 1, providing a binary combination for addressing.

- **Data Lines:** Each address line can contain 8 bits of data (since there are 8 data lines).

To find the total capacity in bits:

\[ \text{Total Capacity} = 2^{13} \times 8 \]

\[ \text{Total Capacity} = 8192 \times 8 = 65536 \text{ bits} \]

Therefore, the chip capacity is 65,536 bits or 8,192 bytes (1 byte = 8 bits).

**Question 10**

When Select = 0, Dout will read ______.

[Diagram Description]
The diagram illustrates a simple circuit with a transistor. It has the following components:

- A horizontal line labeled "Select" on the left that connects to the base of the transistor.
- A transistor is depicted with an arrow pointing towards the emitter, indicating an NPN type.
- The collector of the transistor is connected to a horizontal line on the top labeled "Dout".
- The emitter of the transistor is connected to a resistor that is grounded.
