  • Publication number: 20240162318
    Abstract: A thin film transistor includes a gate electrode embedded in an insulating layer that overlies a substrate, a gate dielectric overlying the gate electrode, an active layer comprising a compound semiconductor material and overlying the gate dielectric, and a source electrode and drain electrode contacting end portions of the active layer. The gate dielectric may have thicker portions over interfaces with the insulating layer to suppress hydrogen diffusion therethrough. Additionally or alternatively, a passivation capping dielectric including a dielectric metal oxide material may be interposed between the active layer and a dielectric layer overlying the active layer to suppress hydrogen diffusion therethrough.

  • Patent number: 11971782
    Abstract: Systems and methods for a controller including controller memory and logic are presented herein. The logic is configured to control access to a persistent storage media and, in response to one or more commands, the logic determines an intermediate parity value based on a first parity calculation, and using the intermediate parity value determines a final parity value based on the intermediate parity value and a second parity calculation. Determining the intermediate parity value includes sending a uni-directional command to read an old data value from an address indicated in the uni-directional command, perform an exclusive-or operation on the old data value and a new data value indicated in the uni-directional command to determine the intermediate parity value and store, in the persistent storage media, the intermediate parity value at a location associated to an index indicated in the uni-directional command.
