Abstract
A cross-point memory includes a plurality of memory devices, with each device comprising a memory layer between first and second address lines. In one preferred embodiment, the memory layer comprises an OTS (Ovonic Threshold Switch) film and an antifuse film. In another preferred embodiment, the memory layer comprises an OTS film having a first switch voltage (i.e. forming voltage V) greater than all subsequent switch voltages (i.e. threshold voltage V). The cross-point memory is preferably a three-dimensional one-time-programmable memory (3D-OTP), including horizontal 3D-OTP and vertical 3D-OTP.
