Abstract
A memory, an operation method thereof, and a memory system are provided. The memory includes: a memory cell array including memory strings each including memory cells and top select transistors; top select gate lines coupled to top select transistors; word lines coupled to memory cells; and a peripheral circuit coupled to top select gate lines and word lines and configured to: apply a first pulse to a first word line of word lines, such that a voltage of the first word line reaches a first target voltage at a first time instant; apply a second pulse to a first top select gate line of top select gate lines adjacent to the first word line, such that a voltage of the first top select gate line reaches a second target voltage at a second time instant that is later than the first time instant.
