Abstract
A self-tracking sense amplifier strobing circuit and process to provide a sense amplifier enable signal in order to reliably control memory read operations over a wide variety of processing conditions. An array of self-tracking memory cells is configured to store a fixed value and includes at least a first tracking cell coupled to receive a wordline enable signal. First and second bitlines are coupled to the first array with the first bitline to be coupled to a power source. An output coupled to the second bitline is asserted to provide a sense amplifier enable signal when the second bitline reaches a predetermined voltage in response to the wordline enable signal being received by the tracking cell.
