Memory Types

Memory Types

1. Static Ram (SDRAM)

   • -very fast memory -very expensive memory -very big memory -used often in processor caches-L1,L2,L3 -no refreshing,but still volatile

2. Dynamic Random Access Memory (DRAM)

   • -the RAM we know and love -Dynamic=Needs constant refreshing ~without refreshing the data in memory disappears

3. Synchronous DRAM (SDRAM)

   • -don't confuse SDRAM with static RAM (SRAM) -SDRAM is synchronous with the common system clock -133 MHz clock=PC133
