A multi-phase charge pump continuously pumps to establish a DC voltage outside the range of supply and reference voltages. The multi-phase charge pump in one embodiment includes four stages operating in a ring with a four-phase clock. Each stage includes a three-mode charge pump that generates and provides reset and control signals to other stages. Each stage includes a pass transistor having a gate driven in excess of the DC voltage for efficient transfer of charge. The gate drive signal from a first stage is coupled to a next stage in the ring where it is used to generate the next gate drive signal. Each gate drive signal corresponds to one waveform having a phase skewed in time so that each stage in the ring is operating in a different mode. In a method of use, a first stepped voltage is developed on a first capacitor and selectively coupled to a second capacitor to develop a second stepped voltage of greater absolute value. The second stepped voltage gates charge transfer from a first stage and enables the selective coupling in a next stage in a sequence of pump stages. The pump stages include protection circuits protecting high-voltage nodes during burn-in testing. The charge pump includes a burn-in detector circuit for detecting burn-in conditions and for turning on the protection circuits and a pump regulator for regulating the output of the charge pump.

The present invention pertains to implementing a dual poly process in forming a transistor based memory device. The process allows buried bitlines to be formed with less energy and to shallower depths than conventional bitlines to save resources and space, and to improve Vt roll-off. Oxide materials are also formed over the buried bitlines to improve (e.g., increase) a breakdown voltage between the bitlines and wordlines, thus allowing for greater discrimination between programming and erasing charges and more reliable resulting data storage. The process also facilitates a reduction in buried bitline width and thus allows bitlines to be formed closer together. As a result, more devices can be “packed” within the same or a smaller area.
