Patent number: 11705206Abstract: Apparatuses and techniques are described for modifying program and erase parameters in a memory device in which memory cells can be operated in a single bit per cell (SLC) mode or a multiple bits per cell mode. In one approach, the stress on a set of memory cells in an SLC mode is reduced during programming and erasing when the number of program-erase cycles for the block in the SLC mode is below a threshold. For example, during programming, the program-verify voltage and program voltages can be reduced to provide a shallower than normal programming. During erasing, the erase-verify voltage can be increased while the erase voltages can be reduced to provide a shallower than normal erase. When the number of program-erase cycles for the block in the SLC mode is above the threshold, the program and erase parameters revert to a default levels.Type: GrantFiled: August 17, 2021Date of Patent: July 18, 2023Assignee: SanDisk Technologies LLCInventors: Abu Naser Zainuddin, Jia Li, Jiahui Yuan, Bo Lei
