Abstract
A memory circuit to reduce active power is disclosed (FIG.). The circuit includes a sense amplifier (). A first bit line (BL) is coupled to a memory array. A second bit line (BLB) that is a complementary bit line to the first bit line is also coupled to the memory array. A first transistor (TG) is coupled between the first bit line (BL) and the sense amplifier. A second transistor (TG) is coupled between the second bit line (BLB) and the sense amplifier. A first drive circuit () is coupled between the sense amplifier and the first bit line and is operable to drive a first data signal from the sense amplifier onto the first bit line when the second transistor is off.
