    摘要: A SONOS memory device, and a method of erasing data from the same, includes injecting charge carriers of a second sign into a trapping film, which traps charge carriers of a first sign to store data therein. The charge carriers of the second sign are generated by an electric field formed between one of a first and second electrodes contacting at least one bit line and a gate electrode contacting a word line. A blocking film may be provided between the gate electrode and the trapping film. The charge carriers of the second sign may be hot holes. This erasing improves erasing speed, thereby improving performance of the SONOS memory device.

    摘要: A non-volatile semiconductor memory device comprises a substrate including a source region, a drain region and a channel region provided between the source region and the drain region with a gate stack located above the channel region with a metal gate located above the gate stack. The metal gate is comprised of a metal having a specific metal work function relative to a composition of a layer of the gate stack that causes electrons to travel through the entire thickness of the blocking layer via direct tunneling. The gate stack preferably comprises a multiple layer stack selected from a group of multiple layer stacks consisting of: ONO, ONH, OHH, OHO, HHH, or HNH, where O is an oxide material, N is SiN, and H is a high κ material.

    摘要: A silicon-oxide-nitride-oxide-silicon (SONOS) memory device includes a memory type transistor including a gate with a SONOS structure on a semiconductor substrate. The gate is formed by sequentially stacking a tunneling oxide layer, a memory node structure including a trap site having nano-sized trap elements in which charges passing through the tunneling oxide layer are trapped, and a gate electrode. The nano-sized trap elements may be a crystal layer composed of nanocrystals that are separated from one another to trap the charges. The memory node structure may include additional memory node layers which are isolated from the nano-sized trap elements.
