Patent ID: 7049628

Claim:
A semiconductor memory cell including a field-effect transistor device based on organic semiconductor material, the field-effect transistor device comprising: a first source/drain region, a second source/drain region, a channel region formed between said first source/drain region and said second source/drain region, a gate region having a gate electrode configuration with a first gate electrode, and an insulation region insulating said gate region from said channel region, said channel region having or being formed from an organic semiconductor material; and at least one modulation region configured between said first gate electrode of said gate electrode configuration and said insulation region; different information states being detectable and/or representable as different electric currents flowing through said channel region when a given electrical potential difference is applied between said first source/drain region and said second source/drain region; said modulation region including modulation material having at least two states; said modulation region being controllably modulatable between said states to electromagnetically influence said channel region, in accordance with said states, for a given electrical potential difference applied between said first gate electrode and said first and second source/drain regions; and said modulation material of said modulation region enabling a capacitance modulation, said modulation material having a modulatable property selected from a group consisting of a specific electrical conductivity, a dielectric property, and a polarization property.
