Document DL0114 Version 0.9 Page 1OverviewThe 32 Bit RIMM® module is a general purpose high-performance line of memory modules suitable for use in a broad range of applications including computer memory, personal computers, workstations, and other applications where high bandwidth and low latency are required. The 32 Bit RIMM module consists of 256Mb/288Mb RDRAM® devices. These are extremely high-speed CMOS DRAMs organized as 16M words by 16 or 18 bits. The use of Rambus Signaling Level (RSL) tech-nology permits the use of conventional system and board design technologies. RIMM 3200 modules support 800MHz transfer rate per pin, resulting in total module bandwidth of 3200MB/s or 3.2GB/s. RIMM 4200 modules support 1066MHz transfer rate per pin, resulting in total module bandwidth of 4200MB/s or 4.2GB/s. The 32 Bit RIMM module provides two independent 16 or 18 bit memory channels to facilitate compact system design. The "Thru" Channel enters and exits the module to support a connection to or from a controller, memory slot, or termination. The "Term" Channel is terminated on the module and supports a connection from a controller or another memory slot.The RDRAM architecture enables the highest sustained bandwidth for multiple, simultaneous, randomly addressed memory transactions. The separate control and data buses with independent row and column control yield over 95% bus efficiency. The RDRAM device multi-bank architecture supports up to four simultaneous transactions per device.Related DocumentationDatasheets for RDRAM memory system components are available on the web at www.rdram.com.
