PRELIMINARY DATA SHEET
128MB 32-bit Direct Rambus DRAM RIMMModule
MC-4R128FKK8K (32M words × 18 bits × 2 channels)
Description
The 32-bit Direct Rambus RIMM module is a general-
purpose 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.
Features
128MB Direct RDRAM storage and 128 banks total
on module
2 independent Direct RDRAM channels, 1 pass
through and 1 terminated on 32-bit RIMM module
High speed 800MHz Direct RDRAM devices
232 edge connector pads with 1mm pad spacing
Module PCB size: 133.35mm × 39.925mm ×
1.27mm
Gold plated edge connector pads contacts
Serial Presence Detect (SPD) support
Operates from a 2.5V (±5%) supply
Low power and power down self refresh modes
Separate Row and Column buses for higher
efficiency
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 RDRAMarchitecture 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.
