Модуль памяти Hewlett-Packard (HP) 512MB PC800 (800MHz) RAMBUS SPS-MEM RIMM, p/n: 239067-001, 402837-872

The Rambus® RIMM™ module is a general purpose high-performance memory module 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 Rambus RIMM module consists of 256Mb/288Mb Direct Rambus DRAM devices. These are extremely high-speed CMOS DRAMs organized as 16M words by 16 or 18 bits. The use of Rambus Signaling Level (RSL) technology permits 600 MHz, 711 MHz or 800 MHz 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-bank architecture supports up to four simultaneous transactions per device.
