Unformatted text preview: 3. What is the size of the row decoder for a 32 kbit memory (128 rows and 256 columns?) It’s a 7-to-128 decoder 4. What are the two fabrication techniques of making a NOR-based ROM array? 1) Metal-to-diffusion contacts can be removed to realize a bit 1, using a mask 2) Using a mask, transistors can be selectively implanted such that their voltage threshold is increased to have a permanent off transistor (read slides 31 to 36 for more details.) 5. Example 10.1 Review slides 37 to 42....
