First claim
Opening claim text (preview).
What is claimed is: 1. A memory device, comprising: an elongated silicon channel including a body region; a number of memory cell gates disposed along a length of the body region, each of the plurality of gates being separated from the body region by respective charge storage structures; wherein the elongated silicon channel further comprises a first recombination region located at a first end, and a second recombination region located at a second end, the first and second rec…
