LOW-POWER DESIGN TECHNOLOGY

Low-power DRAM technology is increasingly important for general memory use (12). Since the current memory market tends to explore outdoor usage, the battery-operable feature

is a crucial requirement for memories. In general, total power consumption of the DRAM chip (P), which is operated at VDD and cycle time tRC, can be expressed as follows:

There are several effective methods to reduce the power consumption.

Special care on supply voltage VDD, bit line capacitance charge QBT, and dc current component IDC could minimize the power consumption effectively
