Which memory architecture requires that either all memory slots are populated or a continuity module is used?

1. SIMM

2. Rambus

3. DIMM

4. SO-DIMM

The correct answer is: Rambus

The Rambus memory architecture is characterized by its requirement for specific memory configurations in order to function properly. It mandates that if you are using RIMM (Rambus Inline Memory Module) slots, all slots must be filled with RIMMs or at least one slot must be filled with a continuity module (also known as a CRIMM, or Continuity RIMM) if not all the slots are populated. This necessity is due to its design, which is optimized for high speeds and bandwidth, making it reliant on proper termination to minimize signal reflections and ensure stable operation. RIMM memory technology operates differently from other architectures such as DIMMs, SO-DIMMs, or SIMMs, which typically allow for more flexible configurations. For instance, DIMMs can function with one or more slots populated, offering greater versatility. SO-DIMMs are smaller variants used primarily in laptops, while SIMMs were an earlier technology that doesn't impose the same requirements as Rambus. The unique design requirements of Rambus memory make it essential to adhere to the guidelines around slot population, thereby highlighting its specific architecture needs compared to other types.
