Abstract:
Embodiments of the disclosure are drawn to apparatuses and methods for generating a refresh address locally at a memory bank. The memory bank may include or be associated with a bank logic circuit that latches an initial refresh address from a global row address bus for a first pump of a refresh operation. The bank logic circuit then updates the latched refresh address received to generate a new refresh address for a second pump of the refresh operation. A memory device may include multiple memory banks that share the global row address bus.
