Apparatuses for decreasing write pull-up time and methods of use

Abstract

Embodiments of the disclosure are drawn to apparatuses and methods for charging memory data lines when a high charge level is to be written to a memory. The apparatus may include a write amplifier that includes one or more additional pull-up drivers for charging the memory data lines. Control logic may control when additional pull-up drivers are activated. Control logic may control when main data lines are coupled to shared data lines. Methods for charging memory data lines may include providing control signals that indicate which main data lines are coupled to shared data lines and when a write command is received. Methods may include providing a signal that is indicative of the data to be written. The control signals and signal indicative of the data to be written may be used to activate one or more pull-up drivers to charge one or more data lines.
