| 摘要 |
A memory device and related methods are described. The memory device includes a plurality of cells, each cell including a MOSFET having a source coupled to a first end of a channel, a drain coupled to a second end of the channel, a gate formed on a gate insulator and extending from the source to the drain and a plurality of conductive islands, each surrounded by an insulator, formed in the channel. The islands have a maximum dimension of three nanometers. The surrounding insulator has a thickness of between five and twenty nanometers. Each island and surrounding insulator is formed in a pore extending into the channel. As a result, the memory cells are able to provide consistent, externally observable changes in response to the presence or absence of a single electron on the island.
