The bistable resistance random access memory comprises two memory layer stacks per memory cell, the bistable resistance random access memory operates in four logic states, a logic “00” state, a logic “01” state, a logic “10” state and a logic “11” state. The relationship between the four different logic states can be represented mathematically by the two variables n and f and a resistance R.

    摘要: A non-volatile method with a self-aligned RRAM element. The method includes a lower electrode element, generally planar in form, having an inner contact surface. At the top of the device is a upper electrode element, spaced from the lower electrode element. A containment structure extends between the upper electrode element and the lower electrode element, and this element includes a sidewall spacer element having an inner surface defining a generally funnel-shaped central cavity, terminating at a terminal edge to define a central aperture; and a spandrel element positioned between the sidewall spacer element and the lower electrode, having an inner surface defining a thermal isolation cell, the spandrel inner walls being spaced radially outward from the sidewall spacer terminal edge, such that the sidewall spacer terminal edge projects radially inward from the spandrel element inner surface. ARRAM element extends between the lower electrode element and the upper electrode, occupying at least a portion of the sidewall spacer element central cavity and projecting from the sidewall spacer terminal edge toward and making contact with the lower electrode. In this manner, the spandrel element inner surface is spaced from the RRAM element to define a thermal isolation cell adjacent the RRAM element.

    摘要: A process in the manufacturing of a resistor random access memory with a confined melting area for switching a phase change in the programmable resistive memory. The process initially formed a pillar comprising a substrate body, a first conductive material overlying the substrate body, a programmable resistive memory material overlying the first conductive material, a high selective material overlying the programmable resistive memory material, and a silicon nitride material overlying the high selective material. The high selective material in the pillar is isotropically etched on both sides of the high selective material to create a void on each side of the high selective material with a reduced length. A programmable resistive memory material is deposited in a confined area previously occupied by the reduced length of the poly, and the programmable resistive memory material is deposited into an area previously occupied by the silicon nitride material.

    摘要: A method of manufacturing a non-volatile semiconductor memory device includes forming a sub-gate without an additional mask. A low word-line resistance is formed by a metal silicide layer on a main gate of the memory device. In operation, application of a voltage to the sub-gate forms a transient state inversion layer that serves as a bit-line, so that no implantation is required to form the bit-line.
