This device stores digital computer information as an analog signal on a ferroelectric transistor that allows the data to be retrieved even after power is removed from the device. It stores many bits of data on two transistors instead of the normal 6 transistors for one bit. It can read and write this data at high speed with an unlimited number of cycles. The data will be retained for long periods of time without power.

On-chip spectrometer using vertical hetero structure of long pass optical filters and silicon films

1. Novelty This art describes a ultra-lightweight, on-chip spectrometer capable of multi- wavelength imaging with high efficiency and narrow bandwidth.

Development of this capability directly relates to all current and future NASA efforts relevant to the multi-spectrum imaging and hyper-spectrum imaging for both remote sensing and in situ missions.
