The Rambus RIMM module consists of 128Mb/144Mb Direct Rambus DRAM devices. These are extremely highspeed CMOS DRAMs organized as 8M words by 16 or 18 bits. The use of Rambus Signaling Level (RSL) technology permits 600MHz or 800MHz transfer rates while using conventional system and board design technologies. RDRAM devices are capable of sustained data transfers at 1.25 ns per two bytes (10ns 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's 32-banks architecture supports up to four simultaneous transactions per device. trac (Row Access Time) ns 53 45 40 53 45 40 53 45 40 53 45 40 53 45 40 Part Numbera 32M x 16/18 KMMR16/18R84C-RG6 KMMR16/18R84C-RK8 KMMR16/18R84C-RM8 KMMR16/18R86C-RG6 KMMR16/18R86C-RK8 KMMR16/18R86C-RM8 KMMR16/18R88C-RG6 KMMR16/18R88C-RK8 KMMR16/18R88C-RM8 KMMR16/18R8CC-RG6 KMMR16/18R8CC-RK8 KMMR16/18R8CC-RM8 KMMR16/18R8GC-RG6 KMMR16/18R8GC-RK8 KMMR16/18R8GC-RM8 Features ♦ High speed 800 and 600MHz RDRAM storage ♦ 184 edge connector pads with 1mm pad spacing ♦ Maximum module PCB size : 133.5mm x 34.93mm x 96M x 16/18 -RG6 -RK8 -RM8 128M x 16/18 -RG6 -RK8 -RM8 1.37mm (5.21” x 1.375” x 0.05”) ♦ Each RDRAM has 32 banks, for a total of 512, 384, 256, 192, or 128 banks on each 256/288MB, 192/216MB, 128/144MB, 96/108MB, or 64/72MB module respectively ♦ Gold plated edge connector pad contacts ♦ Serial Presence Detect(SPD) support ♦ Operates from a 2.5 volt supply (±5%) ♦ Low power and powerdown self refresh modes ♦ Separate Row and Column buses for higher efficiency ♦ RDRAMs use µ−BGA package type a. -S designator is used for modules with lower self-refresh current. Form Factor The Rambus RIMM modules are offered in a 184-pad 1mm edge connector pad pitch form factor suitable for 184 contact RIMM connectors. The RIMM module is suitable for desktop and other system applications. Note: On two sided modules, RDRAMs are also installed on bottem side of PCB.
