Patent number: 12293101Abstract: Methods, systems, and devices for data relocation operation techniques are described. A memory system may include blocks of memory cells, for example, within a non-volatile memory device of the memory system. The memory system may identify a command to perform a data relocation operation associated with a block of memory cells and may select between a first procedure and a second procedure for performing the data relocation operation. The memory system may select between the first procedure and the second procedure based on whether one or more parameters associated with the data relocation operation satisfy a threshold. For example, the memory system may select the first procedure if the one or more parameters satisfy the threshold and may select the second procedure if the one or more parameters do not satisfy the threshold. The memory system may perform the data relocation operation using the selected procedure.Type: GrantFiled: January 25, 2024Date of Patent: May 6, 2025Assignee: Micron Technology, Inc.Inventors: Paolo Papa, Luigi Esposito, Massimo Iaculo, Giuseppe D'Eliseo, Alberto Sassara, Carminantonio Manganelli, Salvatore Del Prete

Publication number: 20240394183Abstract: Devices and techniques for corrupted storage portion recovery in a memory device are described herein. A failure event can be detected during a garbage collection operation on a collection of storage portions (e.g., pages) in a memory array. Here, members of the collection of storage portions are being moved from a former physical location to a new physical location by the garbage collection operation. A reference to a former physical location of a possibly corrupt storage portion in the collection of storage portions can be retrieved in response to the failure event. Here, the possibly corrupt storage portion has already been written to a new physical location as part of the garbage collection operation. The possibly corrupt storage portion can then be rewritten at the new physical location using data from the former physical location.Type: ApplicationFiled: August 2, 2024Publication date: November 28, 2024Inventors: Lalla Fatima Drissi, Giuseppe D'Eliseo, Paolo Papa, Massimo Iaculo, Carminantonio Manganelli

Publication number: 20240168654Abstract: Methods, systems, and devices for data block refresh during read access are described. In some instances, when an access command (e.g., a read command) is received, a memory system may determine if the associated block is a PSA block. If the block is PSA block, its data may be provided to a host system to satisfy the read command and the block may either be refreshed or may be designated to be refreshed. For example, the block may be refreshed by copying its data to a write cache and writing the data from the cache to a new block. In other instances, an LBA of the block may be stored (e.g., designated) and the LBA may be refreshed when the memory system is idle.Type: ApplicationFiled: November 8, 2023Publication date: May 23, 2024Inventors: Luca Porzio, Ting Luo, Ciro Feliciano, Giuseppe D'Eliseo
