Abstract
Apparatuses, systems, and methods for direct refresh management (DRFM) commands. A controller provides a DRFM command to a memory along with a row address. A command decoder of the memory provides an activate command and then a pre-charge command along a signal line to a bank. During a tRP time after the pre-charge command before a next activate command, a DRFM sampling command is provided along the signal line which causes the address to be latched in a DRFM latch. Responsive to a later DRFM service command, one or more wordlines based on the address in the DRFM latch are refreshed.
