The Reduced Latency Dynamic Random Access Memory (RLDRAM) Controller is a general-purpose memory controller that interfaces with industry standard RLDRAM. The controller can be configured to function as RLDRAM I, RLDRAM II CIO (Common I/O) or RLDRAM II SIO (Separate I/O). The RLDRAM is a high-speed memory device used mainly in high bandwidth, latency sensitive application like communications, data storage etc. Data is transferred on both edges of the clock, doubling the rate of data transfer. This IP provides an interface between the RLDRAM and the generic bus interface. The RLDRAM controller is designed to support RLDRAM I with target speeds up to 300 MHz DDR and RLDRAM II CIO or SIO modes with target speeds up to 400 MHz DDR.
