Abstract
In one arrangement, a semiconductor memory device can include a sense amplifier circuit () having drive high transistors (P/P), drive low transistors (N/N) and equalization transistors (N-N). Such transistors can have a body bias (VbiasN, VbiasP) that varies according to the operation conditions of the semiconductor memory device. Such variations can include any of: manufacturing process variations, operating temperature, or operating voltage.
