Abstract
A local sensing amplifier and a memory are provided. The local sensing amplifier is connected to a global signal line and is connected to a sense amplifier array by means of a local signal line and a complementary local signal line. The local sensing amplifier transmits a signal on the local signal line to the global signal line when a read control signal is received, and to transmit a signal on the global signal line to the local signal line when a write control signal is received. The local sensing amplifier includes a precharge circuit connected to a preset voltage source, the local signal line and the complementary local signal line. The preset voltage source provides a first voltage in a read-write interval and provide a second voltage in an idle period. The precharge circuit transmits first voltage to the local signal line and the complementary local signal line.
