Abstract:
Apparatuses and methods for reducing row address (RAS) to column address (CAS) delay (tRCD) are disclosed. In some examples, tRCD may be reduced by providing a non-zero offset voltage to a target wordline at an earlier time, such as during a threshold voltage compensation phase of a sense operation. Setting the wordline to a non-zero offset voltage at an earlier time may reduce a time for the wordline to reach an activation voltage, which may reduce tRCD. In other examples, protection against row hammer attacks during precharge phases may be improved by setting the wordline to the non-zero offset voltage.
