128MB 32-bit Direct Rambus DRAM RIMM Module
MC-4R128FKK8K (32M words ×××× 18 bits ×××× 2 channels)
Description
The 32-bit Direct Rambus RIMM module is a generalpurpose high-performance lines 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 latency are required.
The 32-bit RIMM module consists of 288Mb 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 the use of conventional
system and board design technologies. The 32-bit
RIMM modules support 800MHz transfer rate per pin,
resulting in total module bandwidth of 3.2GB/s.
The 32-bit RIMM module provides two independent 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
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.
