Abstract :
This paper gives a study of leakage in 90nm logic CMOS technology, and by analyzing the power constitutions in multi-ported register files and the leakage in different nMOS transistors with different power supply, a low-swing strategy for bit lines is used in saving power. In this paper an 8 read / 4 write ports write-through register file is designed and it dissipates 10.04mW at 500MHz, which save 33.36% power in read operation and 24.8% energy in average. The leakage power on the bit lines also reduces 1.7% by using high threshold voltage transistors in low-swing scheme.
