如果您希望可以时常见面,欢迎标星收藏哦~ 在半导体行业,每一次技术的迭代往往源于对"降本增效"的极致追求。 以近年来火热的RRAM为例,继2024年与维信诺携手完成世界首颗采用嵌入式RRAM(Resistive Random Access Memory,阻变存储器)存储技术AMOLED显示驱动芯片的开发和认证近期之 后,昇显微近日又推出了Ramless+RRAM方案。这不但引领AMOLED显示产业降本革新,还标志 着新型存储技术正式步入大规模商用阶段,更在当前的行业背景下,为显示驱动芯片市场开辟了一 条全新的突围之路。 长期以来,AMOLED显示驱动芯片由于工艺兼容性问题,无法直接在28nm及更先进的逻辑制程中 嵌入传统的Flash存储。因此,行业普遍采用"外置NOR Flash"方案——即在DDIC芯片之外,额外 搭载一颗Flash芯片来存储补偿参数。 这种"外加外带"的模式在过去几年遭遇了严峻挑战:一方面,外置Flash芯片大幅推高封装成本, 挤压终端厂商利润空间;另一方面,传统Flash读写延迟较高,拖累产线效率。特别是现在随着全 球存储供应链的波动,存储器短缺导致的成本上涨和供应不稳定,直接制约了显示 ...
