Aspects of the present disclosure configure a system component, such as memory sub-system controller, to defer performance of an error-correction parity calculation for a block of a memory components of the memory subsystem. In particular, a memory sub-system controller of some embodiments can defer (e.g., delay) performance of an error-correction parity calculation and can defer the error-correction parity calculation such that it is performed at a time when the memory sub-system satisfies an idle state condition.
