Rambus RIMM Modules
Direct RDRAM RIMM Modules
(with 144 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 144 Mbit Direct Rambus DRAM (Direct RDRAM
)
devices. These are extremely high-speed CMOS DRAMs organized as 8M 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
The 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.
