A non-volatile static random access memory has an operating mode, a data backup mode and a data restore mode. The non-volatile static random access memory includes a memory cell and a power saving module. The memory cell includes a latch, a set of latch switch units, a set of backup memory units, a set of backup activation units, a backup setting unit and a driving signal transmission unit. The power saving module includes a control switch unit, a backup determination unit and a restore switch unit. When backup data is different from data stored in the latch, a backup driving signal is generated by a node voltage of the backup memory units and outputted to a backup determination unit, which drives the backup setting unit to turn on according to the backup driving signal, so as to change the backup data in the backup memory units and ensure correct backup.
