With densities up to 256Mbit, RDRAM components are available in volume from leading memory suppliers in a range of speeds from
800MHz to 1200MHz.
For systems requiring upgrade flexibility, RDRAM devices may be configured into single-, dual- or quad-channel RIMM modules to support bandwidths from 1.6 GB/sec to 10.7 GB/sec and system memory capacities up to 8GB. Both RDRAM memory devices and RIMM modules are tested for specification compliance with an extensive validation program that also promotes system interoperability. Additionally, standard RDRAM memory controllers are available in a wide range of ASIC and foundry processes in a variety of different advanced geometries from 0.25 to 0.13 m.
