Overview
The RIMM
module is a general purpose high- performance
memory module suitable for use in a broad range of applica-
tions including computer memory, personal computers,
workstations and other applications where high bandwidth
and low latency are required.
tions including computer memory, personal computers,
workstations and other applications where high bandwidth
and low latency are required.
The RIMM module consists of 256/288Mb 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) technology permits up to
1066 MHz transfer rates while using conventional system
and board design technologies. RDRAM

(7.5ns per 16 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 device's 32-bank architecture
supports up to four simultaneous transactions per device.
