RAM
RAM (Random Access Memory) is a form of computer data storage that stores data and machine instructions currently being used. This volatile memory type allows data to be read or written in almost the same amount of time, regardless of the physical location of data inside the memory.
Key Points:
- Purpose: Acts as a temporary workspace for programs and data.
- Types: Includes DRAM (Dynamic RAM) and SRAM (Static RAM).
- Capacity: Can range from small devices with a few kilobytes to servers with terabytes.
- Speed: Critical factor in determining system performance.
Related Concepts:
- cpu
- Neural Networks
- Transformer Architecture
Notable Implementations:
- In the context of running modern AI models on vintage hardware, such as the 1979 44, RAM capacity is a significant bottleneck. The original setup featured only 64KB of memory, which was later upgraded to 4MB.
