Abstract
A memory comprises a memory cell, a sense amplifier, and a control unit. The memory cell stores a first bit and a second bit. The sense amplifier senses a first cell current and a second cell current corresponding to the first and the second bits respectively with a voltage applying on the memory cell. The control unit determines a digital state of the first bit by comparing a first reference current with the first cell current or by comparing a reference data with a first delta current between the first cell current and the second cell current.
