Disclosed are improved cross-point array memory devices. In one embodiment, a memory device comprises a cross-point array of memory cells, each memory cell including a storage element and a current concentrating feature that concentrates current applied to the storage element. In another embodiment, a memory device comprises a cross-point array of memory cells, each memory cell including a storage element having a preprogrammed filament fuse configured to be disabled during a write procedure.

A system and method for erasing a high-density non-volatile fast memory is presented. In one embodiment the high-density non-volatile fast memory is a modified flash memory having modified flash cells. One embodiment of the system comprises ultra-violet (UV) light windows that permit exposure of the modified flash cells to UV light. The exposure of UV light onto the modified flash cells erases the modified flash cells.

A memory cell has a first and second conductor. The first conductor is oriented in a first direction and the second conductor is oriented in a second direction. The first conductor has at least one edge. A state-change layer is disposed on the first conductor and a control element is partially offset over the at least one edge of the first conductor. The control element is disposed between the first and second conductors. Preferably the state-change layer is a direct-tunneling or dielectric rupture anti-fuse. A memory array can be formed from a plurality of the memory cells. Optionally, creating multiple layers of the memory cells can form a three-dimensional memory array.

The invention includes an electronic memory structure. The electronic memory structure includes a substrate. A substantially planar first conductor is formed adjacent to the substrate. An interconnection layer is formed adjacent to the first conductor. A phase change material element is formed adjacent to the interconnection layer. The interconnection layer includes a conductive interconnect structure extending from the first conductor to the phase change material element. The interconnect structure includes a first surface physically connected to the first conductor. The interconnect structure further includes a second surface attached to the phase change material element. The second surface area of the second surface is substantially smaller than a first surface area of the first surface. A substantially planar second conductor is formed adjacent to the phase change material element.

The invention relates to a process for the preparation of resols by reacting phenolic compounds with aldehydes with catalysis by metal salts whose cation can easily be precipitated as low-solubility salts in industrial processes. In this process, a dispersant is added to the reaction mixture comprising phenolic compound, aldehyde and metal salt before, during or after the condensation reaction, and a complexing agent is admixed after the condensation reaction is complete and after the dispersant has been admixed. The resultant resins are transparent even after neutralization using sulphuric acid.
