Patent number: 11934689Abstract: A processing device detects a read operation at a memory device that is directed at a word line group from among multiple word line groups of the memory device. The processing device increments a read counter associated with the word line group based on the read operation being directed at the word line group. The processing device determines the read counter exceeds a read-disturb threshold and performs read-disturb handling on the word line group in response to determining the read counter exceeds the read-disturb threshold.Type: GrantFiled: November 10, 2022Date of Patent: March 19, 2024Assignee: Micron Technology, Inc.Inventors: Michael G. Miller, Ashutosh Malshe, Gianni Stephen Alsasua, Renato Padilla, Jr., Vamsi Pavan Rayaprolu, Kishore Kumar Muchherla, Harish Reddy Singidi

Patent number: 11024394Abstract: A memory sub-system can be determined to be operating within a target operating characteristic based on a threshold success rate associated with error control operations using a particular parameter. Upon determining that the memory sub-system is operating within the target operating characteristic, a sticky read mode is entered by performing subsequent read operations using the particular parameter. It is determined that additional error control operations are triggered for at least a first threshold number of read operations using the particular parameter during the sticky read mode. Upon determining that the additional error control operations are triggered for at least the first threshold number of read operations using the particular parameter during the sticky read mode, the sticky read mode is exited by performing further read operations using a default parameter associated with the memory sub-system.Type: GrantFiled: April 9, 2020Date of Patent: June 1, 2021Assignee: MICRON TECHNOLOGY, INC.Inventors: Harish Singidi, Kishore Muchherla, Ashutosh Malshe, Vamsi Rayaprolu, Sampath Ratnam, Renato Padilla, Jr., Michael Miller
