Abstract

A negative bitline write assist circuit includes a bias capacitor configured to facilitate driving the capacitance of a bitline. The negative bitline write assist circuit may be modularly replicated within a circuit to change the amount of negative voltage on the bitline during write operations. The bitline write assist circuit may be coupled directly to the bitline, removing the need to add a pull-down transistor to the write driver.
