Publication number: 20240176539Abstract: This application describes systems and methods for facilitating memory access in flash drives. An example method performed by a memory controller may include receiving, from a host, a write command comprising data to be written into a flash memory; splitting the data into a first portion and a second portion; storing the first portion into a static random-access memory (SRAM) in the memory controller; storing the second portion into a dynamic random-access memory (DRAM) communicatively coupled with the memory controller; initiating a configuration operation corresponding to the write command; fetching the first portion from the SRAM and the second portion from the DRAM in response to the flash translation layer indicating a ready status to store the data into the flash memory; combining the fetched first portion and the fetched second portion; and storing the combined first portion and the second portion into the flash memory.Type: ApplicationFiled: February 24, 2023Publication date: May 30, 2024Inventors: Jifeng WANG, Yuming XU, Wentao WU, Fei XUE, Xiang GAO, Jiajing JIN

Publication number: 20240143225Abstract: A solid state drive (SSD) includes an NAND memory and an SSD controller. The SSD controller includes an interface coupled to a host machine, a nonvolatile memory controller coupled to the interface, and a processor coupled to the nonvolatile memory controller. The SSD controller is configured to: receive, via the interface, a write command from the host machine; process, by the nonvolatile memory controller, the write command; transmit, from the nonvolatile memory controller to the processor, a system message; process, by the processor according to Zoned Namespaces (ZNS) protocol, the system message; obtain, by the nonvolatile memory controller via the interface, host data for storage from the host machine; and write the host data to the NAND memory based on a result of processing the system message. Processing the system message by the processor and obtaining the host data by the nonvolatile memory controller are executed in parallel.Type: ApplicationFiled: February 24, 2023Publication date: May 2, 2024Inventors: Yuming XU, Jiu HENG, Fei XUE, Wentao WU, Jifeng WANG, Jiajing JIN, Xiang GAO

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
