HYR16xx49G 64MB & 128MB Rambus RIMM Modules Direct RDRAM RIMM Modules (with 288 Mbit RDRAMs) Overview The Direct Rambus™ RIMM™ module is a general purpose high-performance memory subsystem 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 Direct Rambus RIMM module consists of 288 Mbit Direct Rambus DRAM (Direct RDRAM™) devices. These are extremely high-speed CMOS DRAMs organized as 16M words by 18 bits. The use of Rambus Signaling Level (RSL) technology permits 600 MHz to 800 MHz transfer rates while using conventional system and board design technologies. Direct RDRAM devices are capable of sustained data transfers at 1.25 ns per two bytes (10 ns per sixteen bytes). 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's 32-bank architecture supports up to four simultaneous transactions per device. Form Factor These family of 64MByte and 128MByte Rambus RIMM modules are offered in a 184-pad 1 mm edge connector pad pitch form factor suitable for 184 contact RIMM connectors. The RIMM module is suitable for desktop and other system applications. The next figure shows an eight device Rambus RIMM module without heat spreader. Features 64 MByte and ...
