Abstract:
Apparatuses for executing interrupt refresh are described. An example apparatus includes: memory banks, a sampling timing generator circuit, bank sampling circuits and a command state signal generator circuit that provides a command state signal responsive to a command. Each memory bank includes a latch that stores an address for interrupt refresh. The sampling timing generator circuit receives an oscillation signal and provides a trigger signal of sampling the address. Each bank sampling circuit is associated with a corresponding memory bank. Each bank sampling circuit provides a sampling signal to the latch in the corresponding memory bank responsive to the trigger signal of sampling the address. The sampling timing generator circuit provides the trigger signal of sampling the address, responsive, at least in part, to the command state signal, and the latch stores the address, responsive, at least in part, to the at least one trigger signal of sampling the address.
