Abstract
The present application provides an operation method of a memory, a memory, and a memory system, and relates to the technical field of semiconductor chips. The memory includes a memory block and a plurality of word lines coupled to the memory block. The operation method includes: applying a pass voltage to the plurality of word lines after a first read operation and before a second read operation; applying the pass voltage to the plurality of word lines in a pre-turn-on stage of the second read operation; and applying a first read voltage to a first word line of the plurality of word lines in a read stage of the second read operation, wherein the pass voltage is greater than the first read voltage. In the present application, the pass voltage is applied to the plurality of word lines after the first read operation and before the second read operation.
