来扬科技股份有限公司( Lyontek Inc.)，成立于2003年，总公司位在新竹科学园区，为IC设计公司。我们专长于静态随机存取记忆体Asynchronous SRAM(低功耗SRAM 及 高速 SRAM)之产品设计开发及销售，本公司产品主要应用于：(a)工业用电子产品(b)POS系统(c)消费类电子产品(d)通讯产品(e)汽车工业类电子产品(f)医疗器材类电子产品
SDRAM是Synchronous Dynamic Random Access Memory（同步动态随机存储器）的简称，SDRAM采用3.3v工作电压，带宽64位，SDRAM将CPU与RAM通过一个相同的时钟锁在一起，使RAM和CPU能够共享一个时钟周期，以相同的速度同步工作，与 EDO内存相比速度能提高50%。SDRAM基于双存储体结构，内含两个交错的存储阵列，当CPU从一个存储体或阵列访问数据时，另一个就已为读写数据做好了准备，通过这两个存储阵列的紧密切换，读取效率就能得到成倍的提高。SDRAM不仅可用作主存，在显示卡上的显存方面也有广泛应用
