Publication number: 20240086692Abstract: A semiconductor device may include a non-volatile memory cell structure that may be formed in a back end region of a semiconductor device. The non-volatile memory cell structure may include a floating gate structure in which a portion of a dielectric layer is included between a gate structure and a word line conductive structure. The separation of the gate structure and the word line conductive structure by the dielectric layer results in the gate structure being a floating gate structure. This enables a charge to be selectively stored on the gate structure, even when power is removed from the word line conductive structure. The non-volatile memory cell structure along with a volatile memory cell structure are provided in the back end region of the semiconductor device, such that caching and long-term storage may be performed in the back end region of the semiconductor device.Type: ApplicationFiled: January 5, 2023Publication date: March 14, 2024Inventors: Yun-Feng KAO, Katherine H. CHIANG, Chia Yu LING

Publication number: 20240074137Abstract: A capacitorless dynamic random access memory (DRAM) cell may include a plurality of transistors. At least a subset of the transistors may include a channel layer that approximately resembles an inverted U shape, an ohm symbol (?) shape, or an uppercase/capital omega (?) shape. The particular shape of the channel layer provides an increased channel length for the subset of the transistors, which may reduce the off current and may reduce current leakage in the subset of the transistors. The reduced off current and reduced current leakage may increase data retention in the subset of the transistors and/or may increase the reliability of the subset of the transistors without increasing the footprint of the subset of the transistors. Moreover, the particular shape of the channel layer enables the subset of the transistors to be formed with a top-gate structure, which provides low integration complexity with other transistors in the capacitorless DRAM cell.Type: ApplicationFiled: August 25, 2022Publication date: February 29, 2024Inventors: Yun-Feng KAO, Chia Yu LING, Katherine H.

Patent number: 11288464Abstract: A multi-protocol RFID interrogating system employs a synchronization technique (step-lock) for a backscatter RFID system that allows simultaneous operation of closely spaced interrogators. The multi-protocol RFID interrogating system can communicate with backscatter transponders having different output protocols and with active transponders including: Title 21 compliant RFID backscatter transponders; IT2000 RFID backscatter transponders that provide an extended mode capability beyond Title 21; EGOTM RFID backscatter transponders, SEGOTM RFID backscatter transponders; ATA, ISO, ANSI AAR compliant RFID backscatter transponders; and IAG compliant active technology transponders. The system implements a step-lock operation, whereby adjacent interrogators are synchronized to ensure that all downlinks operate within the same time frame and all uplinks operate within the same time frame, to eliminate downlink on uplink interference.Type: GrantFiled: August 3, 2020Date of Patent: March 29, 2022Assignee: Amtech Systems, LLCInventors: Kelly Gravelle, Steven J.
