摘要

The precharge and equalisation circuit has a precharge N-channel MOS transistor having its drain connected to a supply potential and its source connected to a bit line. A second precharge N-channel MOS transistor has its drain connected to the supply potential and its source connected to a second bit line. The first and second precharge transistors have their gates connected together and to a first input node for receiving a true precharge signal. An equalisation P-channel MOS transistor has its source connected to the first bit line and its drain connected to a common node which is coupled to a current-sinking circuit positioned external to the memory array for sinking current. A second equalisation P-channel MOS transistor has its source connected to the second bit line and its drain connected to the common node. The equalisation transistors have their gates connected together and to a second input node for receiving a complementary equalisation signal.
