TM RIMM Module with 256/288Mb RDRAMs Preliminary Revision History * Rev. 0.95 Date : 2001.07.23 1. Page2, 7, 8, 10, 12 : Add 2D RIMM part Rev. 0.95 / July.01 1 TM RIMM Module with 256/288Mb RDRAMs Preliminary Overview Key Timing Parameters/Part Numbers The`Rambus (R) RIMMTM module is a general purpose high-performance memory 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. The following table lists the frequency and latency bins available from RIMM modules. The Rambus RIMM module consist of 256/288Mb Direct Rambus DRAM devices. These are extremely high-speed CMOS DRAMs organized as 16M words by 16/18 bits. The use of Rambus Signaling Level (RSL) technology permits 600MHz ,711MHz or 800MHz transfer rates while using conventional system and board design technologies. 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 Direct RDRAM's 32-banks architecture supports up to four simultaneous transactions per device. Features w High speed 800,711 and 600 MHz RDRAM storage w 184 edge connector pads with 1 mm pad spacing w Maximum module PCB size: 133.5mm x 34.93mm x 1.37mm(5.21" x 1.375" x 0.05") w Gold plated edge connector pad contacts w Serial Presence Detect(SPD) support w Operates from a 2.5 volt supply (5%) w Powerdown self refresh modes w BGA Package (92 balls) w Separate Row and Column buses for higher efficiency Table 1: Part Number by Frequency and Latency Organization I/O Freq.
