Abstract

A module includes a high speed voltage node, a pre-charging circuit, and a cross coupled circuit. The pre-charging circuit includes a pre-charger configured to pre-charge complementary first and second lines of a memory device to a level of a source voltage. The cross coupled circuit is configured to pull one of the first and second lines to a level of a high speed voltage at the high speed voltage node higher than the level of the source voltage. As such, a memory cell of the memory device can be read at a high speed.
