來揚科技股份有限公司( Lyontek Inc.)，成立于2003年，總公司位在新竹科學(xué)園區(qū)，為IC設(shè)計公司。我們專長于靜態(tài)隨機(jī)存取記憶體Asynchronous SRAM(低功耗SRAM 及 高速 SRAM)之產(chǎn)品設(shè)計開發(fā)及銷售，本公司產(chǎn)品主要應(yīng)用于：(a)工業(yè)用電子產(chǎn)品(b)POS系統(tǒng)(c)消費類電子產(chǎn)品(d)通訊產(chǎn)品(e)汽車工業(yè)類電子產(chǎn)品(f)醫(yī)療器材類電子產(chǎn)品
SDRAM是Synchronous Dynamic Random Access Memory（同步動態(tài)隨機(jī)存儲器）的簡稱，SDRAM采用3.3v工作電壓，帶寬64位，SDRAM將CPU與RAM通過一個相同的時鐘鎖在一起，使RAM和CPU能夠共享一個時鐘周期，以相同的速度同步工作，與 EDO內(nèi)存相比速度能提高50%。SDRAM基于雙存儲體結(jié)構(gòu)，內(nèi)含兩個交錯的存儲陣列，當(dāng)CPU從一個存儲體或陣列訪問數(shù)據(jù)時，另一個就已為讀寫數(shù)據(jù)做好了準(zhǔn)備，通過這兩個存儲陣列的緊密切換，讀取效率就能得到成倍的提高。SDRAM不僅可用作主存，在顯示卡上的顯存方面也有廣泛應(yīng)用
