Abstract
A memory system includes a first array (of memory cells) and a second array (of write assist circuits) arranged into columns each including a bit line and a bit_bar line coupled to corresponding memory cells of the first array and a corresponding at least one write assist circuit of the second array, each write assist circuit including: latch and memory-adapted third and fourth NMOS transistors. The latch includes: memory-adapted first PMOS and first NMOS transistors connected in series between a power-supply voltage and a first node selectively connectable to a ground voltage; and memory-adapted second PMOS transistor and second NMOS transistors connected in series between the power-supply voltage and a second node selectively connectable to ground voltage. The third NMOS transistor is connected in series between the first node and ground voltage; and the fourth NMOS transistor connected in series between the second node and ground voltage.
