Memory and time sequence tracking method thereof

The invention discloses a memory and a time sequence tracking method thereof. The memory comprises at least one global control circuit, at least one tracking driving circuit, multiple memory units, multiple tracking units, multiple tracking control circuits and multiple different tracking routes, wherein the tracking routes are correspondingly built into a memory unit array. According to the memory disclosed by the invention, as at least three tracking routes are arranged at different positions of a memory array, an operational time sequence of the memory can be relatively comprehensively reflected; besides, as a pre-decoding tracking route is additionally arranged before word lines and bit lines are tracked, the tracking accuracy of the time sequence is improved.
