Described is an apparatus for memory write assist which consumes low power during write assist operation. The apparatus comprises: a power supply node; a device operable to adjust voltage on the power supply node; and a feedback unit coupled to the power supply node, the feedback unit to control the device in response to a voltage level of the voltage on the power supply node.

Adaptive and dynamic stability enhancement for memories is described. In one example, the enhancement includes a plurality of sensors each located near a plurality of memory cells to provide a sensor voltage, a controller to receive the sensor voltage and provide a control signal based thereon, and a read/write assist circuit coupled to the controller to adjust a parameter applied to reading from and writing to a memory cell of the plurality of memory cells in response to the control signal.

Adaptive and dynamic stability enhancement for memories

A method and an apparatus for providing a high voltage to a node of a low voltage tolerant CMOS integrated circuit process. In one embodiment, a pull up circuit is coupled between a high voltage source and the node and a pull down circuit is coupled between the node and a second voltage. The pull up circuit is configured to pull the voltage at the node to a high voltage while the pull down circuit is configured to the voltage at the node to a lower voltage. The pull down circuit includes a pair of series coupled n-channel transistors coupled between the node and the second voltage. The n-channel transistor connected to the node is a special n-channel transistor with a drain to substrate junction breakdown that is greater than the drain to substrate junction breakdown voltage of other ordinary n-channel transistors in the process. The special n-channel transistor is manufactured in an ordinary state-of-the-art CMOS integrated circuit process without adding any costly process steps.
