The present disclosure includes methods, devices, and systems for device to device flow control. In one or more embodiments, a system configured for device to device flow control includes a host and a chain of devices, including one or more memory device, coupled to each other and configured to communicate with the host device through a same host port. In one or more embodiments, at least one device in the chain is configured to regulate the flow of data by sending a token in downstream data packets, the token allowing devices downstream from the respective at least one device to send an upstream data packet to the respective at least one device.
