The memory system has a memory component and a processing device that receives, from a host system, a write command and stores data in the memory component, stores the write command in a buffer, and executes at least a portion of the write command. For example, this write buffer capacity can be represented by the host and subsystem write credit values. The processing device determines the amount of available capacity of the buffer that becomes available after execution of at least a portion of the write command, and signals to receive information identifying the amount of available capacity, without a pending information request received from the host system. Transfer to the host system.
