Abstract
Technology scaling has had a great impact on memory in the areas of power and cost, but challenges due to small geometry are hindering this trend. The three mainstream memory technologies are SRAM, DRAM, and Flash. Table 9.1 compares these three technologies with main memory metrics. SRAM primary use has been for embedded memory due to fast access time. DRAM has been used for main memory due to small size and high density. Its slow access time and refreshing requirements prevent it from being used for on-chip. Flash is used for removable and big capacity memory. Its high voltage requirement for write operation prevents it from being used for on-chip.
