Abstract: A bit line is pre-charged to ground. First and second nodes of a latch are coupled to ground and a reference voltage, respectively. A DRAM bitcell is activated, thereby coupling a DRAM cell capacitor to the bit line, and developing a read voltage on the bit line. The bit line is isolated from the latch when the DRAM bitcell is activated. The first node is decoupled from ground, and the bit line is then coupled to the first node, thereby developing the read voltage on the first node. Then, the second node is de-coupled from the reference voltage, and the bit line is isolated from the first node. The latch is activated, amplifying the voltage difference between the first and second nodes, resulting in a read data voltage on the first node. The bit line is recoupled to the first node, applying the read data voltage to the bit line.
