Abstract
In one embodiment, a static random access memory (SRAM) device is provided. The SRAM device includes a memory cell, a bit line couple to the memory cell, a voltage supply line coupled to the memory cell, a control circuitry. The control circuitry is configured to charge a voltage supply line while the voltage supply line is electrically isolated from a bit line. A portion of the charge is transferred from the voltage supply line to the bit line. The voltage supply line is recharged while the voltage supply line is electrically isolated from the bit line storing the transferred portion of the charge. The memory cell is accessed using the recharge on the voltage supply line.
