Abstract
A memory includes a selected bitline coupled to the array of memory cells. A column multiplexer passes a signal on the selected bitline to a sense amplifier input in response to a column enable signal. A multiplexer output conditioner discharges the sense amplifier input and a bitline conditioner precharges and readjusts the selected bitline to a precharge threshold. A sense amplifier produces a data output that is based on the sense amplifier input.
