RPC DRAM

ETRON RPC® DRAM

The Etron RPC® DRAM (RPC®) offers system users unique and valuable advantages. It adopts a wafer-level chip size package (WLCSP, a fan-in wafer-level die-scale package) that is the world's first high-bandwidth DRAM offered in a WLCSP. The x16 256 megabit RPC® DRAM, has half the number of pins compared to similar bandwidth DDR3 products, and only needs 1/10 the PCB area. Thus, it can provide a path to both miniaturization and cost reduction. The RPC® DRAM provides the same data bandwidth as a x16 DDR3 – LPDDR3 and therefore is suitable for bandwidth intensive applications such as AV multimedia streaming, but with less than half the IO pin count (24 switching signals).

 

Etron’s RPC® DRAM interfaces to popular FPGA products to create the world's smallest machine learning and artificial intelligence products for video applications based on discrete components. When FPGAs are combined with the miniaturized RPC® DRAM along with standard surface mount PCB technology, systems with minimum Size, Weight, Power and Cost (SWAP-C) result. This lays a solid foundation for the deployment of small form factor AI subsystems in high-volume and size-constrained applications. Since RPC DRAMs use less than half the FPGA IO pins of equivalent bandwidth DDR3, the RPC can double memory bandwidth compared to DDR3 while using fewer pins.
