Abstract

Methods and apparatuses to adjust wordline voltage level are presented. An apparatus includes multiple memory cells arranged in multiple rows. A wordline is configured to couple to one row of the multiple rows for a read or write operation. A wordline driving circuit is configured to provide a voltage level to the wordline to facilitate the read or write operation. A tracking circuit is configured to emulate a characteristic of one of the multiple memory cells. A pull-down circuit is configured to lower the voltage level of the wordline by an amount, based on the tracking circuit, to access the one row of the multiple rows in the read or write operation. A method includes emulating a characteristic of one of multiple of memory cells and lowering a voltage level of the wordline by an amount to access one row of the multiple rows in the read or write operation.
