ABSTRACT:
A memory architecture that employs one or more semiconductor PIN diodes is provided. The memory employs a substrate that includes a buried bit/word line and a PIN diode. The PIN diode includes a non-intrinsic semiconductor region, a portion of the bit/word line, and an intrinsic semiconductor region positioned between the non-intrinsic region and the portion of the bit/word line.
