-
Whose 2021 chip-shortage losses were estimated at $210 billion?

Why must DRAM chips refresh many times a second?
Answer: Leaking charge
Why: SRAM holds bits in loops of transistors instead of capacitors, so it needs no refresh while it has power.
-
How many times a second does a 1 GHz chip tick?
Answer: A billion
Why: Different chip families get different amounts of work done per tick, so gigahertz compares speed best within one family.
-
What does a 'fabless' chip company lack?
Answer: Factories
Why: The fabless model took off in the 1980s, with firms paying contract factories called foundries to make their designs.
-
Which element leaves 'holes' when added to silicon?
