Patent number: 11740819Abstract: 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: September 27, 2021Date of Patent: August 29, 2023Assignee: Micron Technology, Inc.Inventors: Zhao Cui, Eric Kwok Fung Yuen, Guan Zhong Wang, Xinghui Duan, Hua Chen Li

Patent number: 11720489Abstract: 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: GrantFiled: September 2, 2022Date of Patent: August 8, 2023Assignee: Micron Technology, Inc.Inventors: Xinghui Duan, Giuseppe D'Eliseo, Lalla Fatima Drissi, Giuseppe Ferrari, Eric Kwok Fung Yuen, Massimo Iaculo

Patent number: 11705201Abstract: 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: GrantFiled: August 23, 2021Date of Patent: July 18, 2023Assignee: Micron Technology, Inc.Inventors: Paolo Papa, Luigi Esposito, Massimo Iaculo, Eric Kwok Fung Yuen, Gerard J.

Patent number: 11620216Abstract: Disclosed in some examples are memory devices which feature intelligent adjustments to SLC cache configurations that balances memory cell lifetime with performance. The size of the SLC cache can be adjusted during usage of the memory device based upon a write amplification (WA) metric of the memory device. In some examples, the size of the SLC cache can be adjusted during usage of the memory device based upon a write amplification (WA) metric of the memory device and a memory device logical saturation metric (percentage of valid user data written in the device of the total user size).Type: GrantFiled: May 23, 2022Date of Patent: April 4, 2023Assignee: Micron Technology, Inc.Inventors: Xinghui Duan, Guanzhong Wang, Xu Zhang, Eric Kwok Fung Yuen

Patent number: 11341041Abstract: 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: GrantFiled: July 27, 2020Date of Patent: May 24, 2022Assignee: Micron Technology, Inc.Inventors: Zhao Cui, Eric Kwok Fung Yuen, Guan Zhong Wang, Xinghui Duan, Giuseppe D'Eliseo, Giuseppe Ferrari
