Abstract
Methods and apparatuses having an improved write assist scheme are presented. An apparatus includes a power supply node configured to provide power from a power supply to one memory cell to store data; a bitline configured to provide write data to the one memory cell in a write operation; and a discharge circuit configured to selectively discharge the power supply node to the bitline, based on the write data. A method to write into a memory cell with a write assist scheme includes providing power from a power supply to one memory cell via a power supply node, to store data; providing write data to the one memory cell via a bitline in a write operation; and discharging, selectively based on the write data, the power supply node to the bitline.
