Abstract
A memory circuit includes a reference node configured to carry a reference voltage having a reference voltage level, a power supply node configured to carry a power supply voltage having a power supply voltage level, a bit line coupled with a plurality of memory cells, a write circuit configured to charge the bit line by driving a voltage level on the bit line toward the power supply voltage level with a first current, and a switching circuit coupled between the power supply node and the bit line. The switching circuit is configured to receive the voltage level on the bit line, and responsive to a difference between the voltage level received on the bit line and the power supply voltage level being less than or equal to a threshold value, drive the voltage level on the bit line toward the power supply voltage level with a second current.
