Abstract
A serial-to-parallel converter comprises a plurality of amorphous silicon thin-film transistors configured in a plurality of serial-to-parallel converter cells through which data is shifted through a plurality of amorphous silicon thin-film floating-gate transistors. In the event power is cutoff or lost, the floating gate transistors non-volatilely store the data which can be read when power is subsequently turned on. Each cell comprises two stages in which data signals are written before being input into the next stage and next cell. A clock generator receives clocking signals for controlling the shifting of data through the serial-to-parallel converter.
