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
