In some embodiments, the memory device may complete the ECS procedure over multiple refresh commands, namely by performing a read (or read/modify) portion of the ECS procedure while a first refresh command is executed, and by performing a write portion of the ECS procedure while a second refresh command is executed. The ECS procedure described herein may facilitate avoiding signaling conflicts or interferences that may occur between the ECS procedure and other memory operations.
