Abstract
The present disclosure provides control methods and control apparatus thereof and reference current modules of memory decoding systems. An exemplary control method of a memory decoding system comprising a decoder having at least a first PMOS transistor, a second PMOS transistor, a first NMOS transistor, a second NMOS transistor and a fourth NMOS transistor, a memory cell, and at least a first bit line and a second bit line, includes applying a first control signal, being at a logic low level during a first read operation stage of a read operation and at a logic high level during a second read operation stage after the first read operation stage of the read operation, to a gate of the first PMOS transistor; applying a second control signal to a gate of the second PMOS transistor; and applying a fourth control signal to a gate of the first NMOS transistor.
