## FAQs
### Q: What is RDRAM?
A: RDRAM is a type of synchronous dynamic random-access memory (SDRAM) developed by Rambus, Inc. It serves as a form of computer data storage and is considered a specific subclass within the broader SDRAM family of technologies.

### Q: What devices used RDRAM?
A: The provided source material confirms that RDRAM was used by the Nintendo 64 video game console.

### Q: Who developed RDRAM?
A: RDRAM was developed by the American technology company Rambus.

## Why It Matters
RDRAM represents a significant, proprietary branch in the evolution of computer memory. Developed by Rambus as a specific subclass of synchronous dynamic random-access memory (SDRAM), it stands as an example of a specialized memory architecture competing for adoption in the broader market. Its implementation in a major consumer product like the Nintendo 64 demonstrates its viability and role in powering high-performance electronics during its time. The existence of numerous performance-based aliases (like PC800 and PC1066) indicates a family of related technologies designed to meet different specifications. As a distinct entity within the history of RAM, RDRAM's development and application provide a case study in memory technology innovation and market diversification around the turn of the 21st century.

## Notable For
- **Proprietary Development:** It was developed by a single company, Rambus, rather than being a multi-company industry standard from the outset.
- **Use in a Major Gaming Console:** RDRAM was the memory technology chosen for the Nintendo 64, a widely popular video game system.
- **Distinct Naming Convention:** It is known by the module name "RIMM" and a series of performance-specific aliases like PC800 and PC1066, which differentiate it from other memory types.
- **Formal Classification:** It is officially categorized as a "subclass of synchronous dynamic random-access memory," giving it a specific place in the computer science taxonomy.

## Body
### Definition and Classification
RDRAM, an acronym for Rambus Dynamic Random-Access Memory, is a technology developed by Rambus. It is formally classified as a subclass of synchronous dynamic random-access memory (SDRAM), which itself is a type of random-access memory (RAM) used for computer data storage.

### Naming and Identification
The technology is known by several aliases, including:
- Rambus DRAM
- Rambus Dynamic Random Access Memory
- RIMM (Rambus Inline Memory Module)
- Rambus

It is also identified by performance-based names such as PC600, PC700, PC800, PC1066, and PC1200. For procurement and cataloging, it is assigned UNSPSC code 32101623 and Common Procurement Vocabulary code 30236114.

### Usage and History
RDRAM was a relevant memory technology around the year 2000. Its most prominent documented application was its use in the Nintendo 64 video game console. The technology is also associated with computer scientist Sally A. McKee, who received her Ph.D. from the University of Virginia in 1995.
