Publication number: 20240143219Abstract: This application describes systems and methods for facilitating memory access on flash drives. An example method may start with receiving a read command on a flash memory from a host specifying a logic block address (LBA). The flash memory may include a plurality of blocks grouped into a plurality of super blocks, and each of the plurality of blocks may include a plurality of pages. The method may further include determining a zone identification and an LBA offset based on the LBA; determining a flash physical address (FPA) corresponding to the LBA by accessing a mapping table stored in a random access memory (RAM) according to the zone identification and the LBA offset (e.g., the mapping table includes a plurality of FPAs arranged in a plurality of zones corresponding to the plurality of super blocks); and determining a page number and a block identification corresponding to the FPA.Type: ApplicationFiled: February 22, 2023Publication date: May 2, 2024Inventors: Xiang GAO, Fei XUE, Jiajing JIN, Wentao WU, Jiu HENG, Yuming XU, Jifeng WANG

The amplifier includes an input circuit, an output buffer, and several bootstrap structure units. The bootstrap structure units include a TFT and a capacitor. The drain and the gate of the TFT are both connected to the same voltage node. The source of the TFT is connected to one end of the capacitor. The other end of the capacitor is connected to an output signal node. The output buffer is formed by connecting the sources and drains of several TFTs in series. Two ends of the output buffer are respectively connected to an input voltage node and an output signal node. The source of the TFT in each bootstrap structure unit is connected to the gates of the TFTs in one output buffer. The input circuit includes an input signal node, the output signal node, and a grounding node. The present disclosure can increase circuit gain and have a simple structure and low fabrication cost.Type: ApplicationFiled: December 31, 2019Publication date: June 9, 2022Inventors: Rongsheng CHEN, Houbo FAN, Guoyuan LI, Yuming XU, Yuning QIN, Zhaohui WU, Bin LI
