IBM licenses Rambus cell for XDR memory

RAMBUS SAID Big Blue has signed a fresh licence agreement with Rambus to use its XDR memory controller interface cell, called the XIO.

The cell is a high performance low latency controller interface to an XDR DRAM memory subsystem. The general purpose cell, said Rambus, is independent of the logical memory controller, providing a wide on-chip CMOS level signalling interface to the memory controller logic and a high speed differential Rambus signalling level (DRSL) interface to the XDR memory system. µ
