PRELIMINARY DATA SHEET  
256MB 32-bit Direct Rambus DRAM RIMMModule  
EBR25EC8ABKD (64M words × 18 bits × 2 channels)  
Description  
Features  
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.  
256MB Direct RDRAM storage and 256 banks total  
on module  
2 independent Direct RDRAM channels, 1 pass  
through and 1 terminated on 32-bit RIMM module  
High speed 1066MHz/800MHz Direct RDRAM  
devices  
232 edge connector pads with 1mm pad spacing  
The EBR25EC8ABKD consists of 8 pieces 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  
Module PCB size: 133.35mm × 34.925mm ×  
1.27mm  
Gold plated edge connector pads contacts  
Serial Presence Detect (SPD) support  
Operates from a 2.5V supply  
Low power and power down self refresh modes  
technologies.  
The 32-bit RIMM modules support  
1066MHz or 800MHz transfer rate per pin, resulting in  
total module bandwidth of 3.2GB/s.  
Separate Row and Column buses for higher  
efficiency  
RDRAMs uses Chip Scale Package (CSP)  
FBGA package  
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.
