Abstract: Provided are a structure and fabricating method of a new inverter for controlling a threshold voltage of each location when an inverter circuit is manufactured using an organic semiconductor on a plastic substrate. In general, p-type organic semiconductor is stable. Accordingly, when the inverter is formed of only the p-type semiconductor, a D-inverter composed of a depletion load and an enhancement driver has large gains, wide swing width and low power consumption, which is more preferable than an E-inverter composed of an enhancement load and an enhancement driver. However, it is impossible to form a depletion transistor and an enhancement transistor on the same substrate while controlling them by locations.

A logic operator performs a logic operation on the data from the FIFO memory with the keys from the encryption key generator during a data write operation to sequentially encrypt the data. The logic operator performs a logic operation on the encrypted data received from a memory interface with the keys output from the encryption key generator during a data read operation in order to sequentially decode the encrypted data. The second signal is simultaneously generated with one of the write command or the read command.

Abstract: Provided is an inverter having a new structure capable of easily controlling a threshold voltage according to position in fabricating an inverter circuit on a plastic substrate using an organic semiconductor. A driver transistor is formed with a dual-gate structure and a positive bias voltage is applied to the top gate of the driver transistor so that a body effect appears in the organic semiconductor.
