ABSTRACT:
For one disclosed embodiment, an apparatus comprises a first p-type device coupled between a cell voltage node and a storage node, an n-type device coupled between the storage node and a reference voltage node, and a second p-type device to couple the storage node to a bit line in response to a signal on a select line. At least one side of diffusion regions in a substrate to form both the first p-type device and the second p-type device are substantially aligned. Other embodiments are also disclosed.
