Publication number: 20210383872Abstract: Devices and techniques for managing flash memory are disclosed herein. A memory controller may receive a first program request comprising first host data to be written to the flash memory. The flash memory may comprise a number of storage units with each storage unit comprising a number of storage sub-units. If the first host data is less than a remainder threshold, the memory controller may generate a first program data unit comprising the first host data and first log data describing the flash memory. The memory controller may program the program data unit to the first storage unit of the flash memory, where the first log data is written to a first storage sub-unit of the number of storage sub-unit, The memory controller may also store an indication that the first storage sub-unit is invalid.Type: ApplicationFiled: August 23, 2021Publication date: December 9, 2021Inventors: Paolo Papa, Luigi Esposito, Massimo Iaculo, Eric Kwok Fung Yuen, Gerard J.

Patent number: 11132136Abstract: Devices and techniques for variable width superblock addressing are described herein. A superblock width, specified in number of planes, is obtained. A superblock entry is created in a translation table of a NAND device. Here, the superblock entry may include a set of blocks, from the NAND device, that have the same block indexes across multiple die of the NAND device. The number of unique block indexes are equal to the number of planes and in different planes. A request, received from a requesting entity, is performed using the superblock entry. Performing the request includes providing a single instruction to multiple die of the NAND device and multiple data segments. Here, a data segment corresponds to a block in the set of blocks specified by a tuple of block index and die. A result of the request is then returned to the requesting entity.Type: GrantFiled: December 13, 2017Date of Patent: September 28, 2021Assignee: Micron Technology, Inc.Inventors: Zhao Cui, Eric Kwok Fung Yuen, Guan Zhong Wang, Xinghui Duan, Hua Chen Li

Publication number: 20210182189Abstract: A variety of applications can include apparatus and/or methods of operating the apparatus in which storage in the memory device is managed. An allocation can include conducting a garbage collection procedure to free up one or more blocks. In various embodiments, execution of a garbage collection procedure can be based on operation of two tables with respect to a logical to physical mapping table split into logical to physical mapping table regions saved in the memory device. The first table can maintain counts of valid pages in blocks for a logical to physical mapping table region. The second table can include bits to identify logical to physical mapping table regions involved in the garbage collection procedure based on the entries in the first table. Search of the second table can determine logical to physical mapping table regions involved in the garbage collection. Additional apparatus, systems, and methods are disclosed.Type: ApplicationFiled: December 11, 2017Publication date: June 17, 2021Inventors: Xinghui Duan, Giuseppe D'Eliseo, Lalla Fatima Drissi, Giuseppe Ferrari, Eric Kwok Fung Yuen, Massimo laculo

Publication number: 20210141557Abstract: Devices and techniques for NAND logical-to-physical table region tracking are described herein. A write request, including a logical page and data to be written at the logical page, is received at a controller of a NAND device. The NAND controller may then establish an entry in a logical-to-physical (L2P) mapping table between the logical page and a physical page of a physical block of the NAND device to which the data is written. Here, the entry may be in a region of the L2P mapping table that is one of multiple regions. An indication of the region may be written in a data structure corresponding to the physical block.Type: ApplicationFiled: December 21, 2017Publication date: May 13, 2021Inventors: Eric Kwok Fung Yuen, Giuseppe Ferrari, Massimo Iaculo, Lalla Fatima Drissi, Xinghui Duan, Giuseppe D'Eliseo

Publication number: 20200356472Abstract: Devices and techniques for synchronizing NAND logical-to-physical table region tracking are described herein. Table region data structures for physical blocks are maintained. These structures include logical-to-physical (L2P) mapping table portions that point to the respective physical blocks. When garbage collection is performed on a block, table region structures for that block, and another (e.g., the next block to be garbage collected) are read to avoid loading L2P table regions that do not point to the block. If any of the read portions of the L2P table region fail to point to either the block or the other block, these L2P table portions are removed from the loaded table region data structures.Type: ApplicationFiled: July 27, 2020Publication date: November 12, 2020Inventors: Zhao Cui, Eric Kwok Fung Yuen, Guanzhong Wang, Xinghui Duan, Giuseppe D'Eliseo, Giuseppe Ferrari
