    Abstract: A memory device (100) includes a conductive structure (210), a number of dielectric layers (410­430) and a control gate (510). The dielectric layers (410-430) are formed around the conductive structure (210) and the control gate (510) is formed over the dielectric layers (410-430). A portion of the conductive structure (210) functions as a drain region (1005) for the memory device (100) and at least one of the dielectric layers (410-430) functions as a charge storage structure for the memory device (100). The dielectric layers (410-430) may include oxide-nitride-oxide layers.

    Abstract: A system and methodology is provided for verifying erasure of one or more dual bit virtual ground memory cells (10, 82, 84, 86, 88) in a memory device, such as a flash memory. Each of the dual bits (10, 82, 84, 86, 88) has a first or normal bit and a second or complimentary bit associated with the first or normal bit. The system and methodology include verifying and erasure of both a normal bit and a complimentary bit of the cell. The erasure includes applying a set of erase pulses to the normal bit and complimentary bit in a single dual bit cell. The set of erase pulses is comprised of a two sided erase pulse to both sides of the bits in the cell or transistor junction followed by a first single sided erase pulse to one side and a second single sided erase pulse to the other side of transistor junction.

    Abstract: A method for transferring a reduced lithographic image size pattern onto a film (14) on a substrate (12) is disclosed. A photosensitive material having an opening (20) of a minimum size achievable by the limits of lithography is transferred onto a mask layer (16) on a substrate (12) having a film (14) thereon. Reduction in the image size is achieved by establishing sidewalls (28) to the interior vertical surfaces (26) of the opening of the mask layer (16) by depositing a conformal layer (28), followed by anisotropic etching. The dimension of the opening (24) is reduced by the combined thickness of the two opposite sidewalls (28). An anisotropic etching of the film (14) transfers a pattern of openings (30) of a minimum size smaller than possible by lithography.
