As chip design and fabrication costs continue to rise with each new process node, the ability to integrate flexible, cost-effective multi-purpose interfaces becomes increasingly valuable. Traditional multi-modal implementations combine the worst-case signal pin count for the functional blocks of the interface for each memory type growing the pin count, area and cost of the interface with each mode supported. Rambus’ FlexMode™ Interface technology uses a programmable assignment of signaling pins as either data (DQ), or command/address (C/A), to enable multi-modal functionality while minimizing signal pin count, even when combining different signaling techniques such as single-ended and differential. This enables an SoC memory controller to be implemented in a single package design with no additional signal pin overhead. An SoC using FlexMode™ Interface technology can address a broad range of system requirements, from entry-level to high-end, without additional cost.
