A flash controller reliably stores data in NAND FLASH by encoding data using an encoding algorithm, and storing that data across multiple pages of the memory. In one embodiment, true data is accepted by the controller, and the controller in turn creates coded data that is the bit-for-bit complement of the true data. The true data and the coded data are then written to the NAND FLASH on a page by page basis. A property of the coding techniques used is that, in at least some cases, detected errors can be corrected.

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.
