Publication number: 20240107776Abstract: An antiferroelectric field effect transistor (Anti-FeFET) of a memory cell includes an antiferroelectric layer instead of a ferroelectric layer. The antiferroelectric layer may operate based on a programmed state and an erased state in which the antiferroelectric layer is in a fully polarized alignment and a non-polarized alignment (or a random state of polarization), respectively. This enables the antiferroelectric layer in the FeFET to provide a sharper/larger voltage drop for an erase operation of the FeFET (e.g., in which the FeFET switches or transitions from the programmed state to the erased state) relative to a ferroelectric material layer that operates based on switching between two opposing fully polarized states.Type: ApplicationFiled: January 5, 2023Publication date: March 28, 2024Inventors: Chun-Chieh LU, Chih-Yu CHANG, Yu-Chuan SHIH, Huai-Ying HUANG, Yu-Ming LIN

Patent number: 11616431Abstract: A control circuit of a power converter includes a sensing circuit, a ramp signal generation circuit and a PWM circuit. The sensing circuit, coupled to an output circuit, provides a current sensing signal. The ramp signal generation circuit includes a transient circuit and a signal generation circuit. The transient circuit receives the current sensing signal and generates a variable reference voltage. The signal generation circuit provides a ramp signal according to the variable reference voltage. The PWM circuit provides a PWM signal to the output circuit according to the ramp signal. When current sourcing occurs, it continues for a first default time. A transient state during current sourcing continues for a second default time less than first default time. The variable reference voltage is changed from a default value to an adjusted value during the second default time and restored to the default value after the second default time.Type: GrantFiled: October 27, 2021Date of Patent: March 28, 2023Assignee: UPI SEMICONDUCTOR CORP.Inventors: Chih-Lien Chang, Wei-Hsiu Hung, Chun-Ming Lu, Min-Rui Lai
