Static random access memory with p-multi-gate access devices, and on / off switches, and associated operating method

Static random access memory comprising: an array of memory cells (100; 300), which cross-coupled inverters (120, 130, 122, 132) with p-Multi-gate field-effect transistor access devices (110, 112); Word lines (115; 450) connected to the p-Multi-gate field-effect transistor access devices (110, 112) are coupled; and is coupled, a decoding circuit (430) connected to the word lines (450 115); characterized, that the static random access memory comprises an on-off switch (440) connected between ground (420) and the decoding circuit (430) is coupled, and that the on-off switch includes an n-Multi-gate field effect transistor on-off switch (440).
