Abstract
Systems and methods for synchronizing write credits between a host device and a media controller of a memory system comprising a non-volatile memory (NVM), wherein the host device is configured to maintain a write credit (WC) counter implemented in a memory controller of the host device. The WC counter tracks and limits the number of outstanding write commands which may be issued to the NVM. The host device may query the memory system to obtain status of the available write buffer space in the media controller, and adjust the WC counter based on any detected errors in the write buffer space reported in metadata of read packets sent from the memory system.
