/Randomized Or Program-erase-cycle- Dependent Program Verify Scheme
Abstract

In some implementations, a memory device may receive a single-level cell (SLC) program command. The memory device may determine, based on at least one of a randomized variable associated with the memory or a program-erase cycle count associated with the memory, a program verify scheme to be performed when executing the SLC program command. The program verify scheme may be one of a scheme associated with performing a program verify operation on all of the one or more subblocks of memory, a scheme associated with performing the program verify operation on a subblock associated with each odd word line (WL) to be programmed, or a scheme associated with performing the program verify operation on a subblock associated with each even WL to be programmed. The memory device may execute the SLC program command by implementing the program verify scheme.
