Abstract
Embodiments relate to replay suspension in a memory system. One aspect is a system that includes a replay buffer coupled to a memory controller interface, and a replay control coupled to the replay buffer and a memory controller. The replay control is configured to receive an error indication associated with sending data from the memory controller interface to a memory subsystem as part of an operation. A replay pending signal is provided to the memory controller based on the error indication. Based on waiting for a period of time sufficient for the memory controller to provide remaining data associated with the operation to the replay buffer, a replay signal is asserted.
