: SDRAM chips are faster than DRAM chips because they
: (A)transfer data twice for each clock cycle
這是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
我剛剛誤把SDRAM看成SRAM
SDRAM是屬於DRAM的一種 所以應該是一樣都要充放電
: (D)use pipelining techniques
應該現行的每顆RAM都支援管線式處理...
: (E)以上皆是
所以答案應該是...B


我只能說...計概真是博大精深阿....
