Innovative DRAM / RPC DRAM

RPC DRAM®

Etron RPC DRAM® (RPC®) 可提供系统用户独特并具有价值的优势,其採用晶圆级晶粒封装 (WLCSP, 一种扇入型晶圆级晶粒尺寸封装),为全世界第一颗可採用WLCSP之高带宽DRAM。该x16 256Mb RPC DRAM相较于相同带宽的DDR3产品,不仅减少一半的接脚,且仅需1/10的PCB面积,可同时达到小型化与成本降低。RPC DRAM提供与x16 DDR3 - LPDDR3相同的数据带宽,因此适合用在带宽密集需求之应用、如:多媒体影音串流,却只需要不到一半的I/O接口引脚 (24个开关讯号)。

 

钰创RPC DRAM的介面适用于常用的FPGA产品,可互相搭配使用,创造出应用在影像方面、全球最小体积之机器学习及人工智能产品。当 FPGA搭配此小型化RPC DRAM时,仅需使用标准的表面贴装PCB技术,系统即可达到最小尺寸、最轻重量、最低功耗与最佳成本的效果。由于RPC DRAM比起相同带宽的DDR3产品仅需使用FPGA不到一半的I/O引脚数,提供了FPGA可同时搭配两颗RPC的空间,达到较少接脚却带宽加倍的效果。这将为须部署小型化的AI子系统、需求高容量却尺寸受限的应用奠定良好的基础。
