Rambus Dynamic Random-Access Memory (RDRAM) was introduced in the late 1990s by Rambus Inc. as a next-generation memory technology. Developed as a high-performance alternative to the existing SDRAM and later DDR SDRAM, RDRAM aimed to significantly boost memory bandwidth and overall computing efficiency. It was initially targeted at high-end computers and gaming consoles, with the promise of transforming system speed and responsiveness.

Key Features and Architecture

RDRAM introduced a unique architecture that set it apart from traditional memory technologies. It operated on a narrow 16-bit data bus and featured high clock rates, ranging from 400 MHz to 800 MHz. Unlike conventional DIMMs, RDRAM used a point-to-point connection with the memory controller and required heat spreaders due to its higher thermal output. One of the most distinct features of RDRAM was its use of the Rambus Channel, which allowed multiple RDRAM modules to be daisy-chained and communicate efficiently with the CPU.
