Abstract: Examples herein describe techniques for directed refresh management (DRFM) address capture in high-bandwidth memory (HBM). Some examples are based on an activate command that includes a DRFM flag, including examples in which the activate command is received and processed while a bank is open, examples in which an address of a target row is captured without opening the corresponding bank, and examples in which the address of a target row is captured based further on a mode registers. Other examples are based on a precharge command that includes a DRFM flag.
