※ 引述《wakke (冲阿 去掉C)》之铭言： : 台大b卷93 11题 : SDRAM chips are faster than DRAM chips because they : (A)transfer data twice for each clock cycle 这是DDR SDRAM的特性 : (B)are synchronized to the system clock 估狗找到的... Short for Synchronous DRAM, a type of DRAM that can run at much higher clock speeds than conventional memory. SDRAM actually synchronizes itself with the CPU's bus and is capable of running at 133 MHz, about three times faster than conventional FPM RAM, and about twice as fast EDO DRAM and BEDO DRAM. SDRAM is replacing EDO DRAM in many newer computers. : (C)do not have to re-energized as often 我刚刚误把SDRAM看成SRAM SDRAM是属於DRAM的一种 所以应该是一样都要充放电 : (D)use pipelining techniques 应该现行的每颗RAM都支援管线式处理... : (E)以上皆是 所以答案应该是...B 我只能说...计概真是博大精深阿.... --
