Abstract
A bit line pre-charge circuit for a dynamic random access memory (DRAM) uses a charge sharing scheme. The pre-charge circuit includes switching elements disposed between a power voltage node and an output node, capacitors connected between intermediate nodes and ground. The switching elements being operated by successively activated control signals to effectively charge a bit line pair to one half a power voltage using charge sharing between the capacitors.
