MC-4R128FKK8K

PRELIMINARY DATA SHEET 128MB 32-bit Direct Rambus DRAM RIMM Module MC-4R128FKK8K (32M words × 18 bits × 2 channels) Description The 32-bit Direct Rambus RIMM module is a generalpurpose 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. The 32-bit RIMM module consists 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 technologies. The 32-bit RIMM modules support 800MHz transfer rate per pin, resulting in total module bandwidth of 3.2GB/s. 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 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 device multi-bank architecture supports up to four simultaneous transactions per device. Features 1...
