DATA SHEET  
MOS INTEGRATED CIRCUIT  
MC-4R64FKE8D  
Direct Rambus DRAM RIMMTM Module  
64M-BYTE (32M-WORD x 18-BIT)  
Description  
The Direct Rambus RIMM module is a general-purpose high-performance memory module 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.  
MC-4R64FKE8D modules consists of two 288M Direct Rambus DRAM (Direct RDRAM) devices (µPD488588).  
These are extremely high-speed CMOS DRAMs organized as 16M words by 18 bits. The use of Rambus Signaling  
Level (RSL) technology permits 600MHz, 711MHz or 800MHz 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 architecture of the Direct RDRAM 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 Direct RDRAM's 32 banks support up to four simultaneous transactions  
per device.  
Features  
184 edge connector pads with 1mm pad spacing  
64 MB Direct RDRAM storage  
Each RDRAM has 32 banks, for 64 banks total on module  
Gold plated contacts  
RDRAMs use Chip Scale Package (CSP)  
Serial Presence Detect support  
Operates from a 2.5 V supply  
Powerdown self refresh modes  
Separate Row and Column buses for higher efficiency  
Over Drive Factor (ODF) support
