Abstract
A circuit for matching sense amplifier trigger signal timing to data bit line separation timing in a self-timed memory array includes: a source of a self-timed word line signal for a self-timed memory array; a transmission gate coupled to the source of the self-timed word line signal for propagating a timing delay and a ramp rate of the self-timed word line signal in response to a corresponding self-timed word line enable signal; and a selectable number of one or more self-timed pull-down core cells for summing a self-timed bit line drive current of each of the selectable number of one or more self-timed pull-down core cells to generate a sense amplifier trigger signal.
